quality as a function of time

I have been beavering away at my vinyl to digital project the past couple of weeks. There has been some noise about the quality of various digital audio formats. As much as we think CDs are wonderful, with the advent of the SuperAudio CD format, it begins to look more like an arms race. And that’s where it starts to take up a lot of time. (More here and here: note that in the Rosenberg piece, he calls CD audio — what some are using as the high-water mark — as a lossy format. At some point you have to accept that this starts to follow the model of Plato’s shadows on the cave wall: we never quite capture everything, despite all our technology and incompatible data formats. Sometimes it’s not the audio quality that defines the quality of the experience.)

I doubt I’ll be able to tell a lot of difference between a good recording in a less than perfect listening environment (how many of us listen in a tuned and acoustically adjusted music room?) and a not-quite-so-good one in a set of headphones (my Sony earbuds or my Sennheisers). And not all formats are available in all systems: I can use flac on my FreeBSD system but that won’t import into iTunes. It has it’s own “lossless” encoding algorithm but I can only use it on CDs. (Well, it occurs to me I could let it encode WAV files created from vinyl, but I’ve not tried that.)

One of the biggest hassles of all this is dealing with the files and their meaningless names when they’re encoded. As one learns in working through all this, the ID3 tags are where the playback system gets its information from: the human readable filename is for your convenience. So my workflow of digitizing in gramofile, splitting the album sides into tracks (going from 2 to as many as 14 files) and taking those anonymously named WAV files through an mp3 encoder and ending up with a bunch of slightly different anonymously named files gets to be a bit tedious and lacks any feeling of progress.

I had been using bladeenc with a bitrate of 192kbits: sounded OK. Then I looked at LAME and discovered that it can add ID3 tags info as it encodes, as well as make some decisions about bitrate to improve quality, on the fly. A little Google action and I can now save myself a bunch of time (and keystrokes) by tagging all but the track name at the same time as I encode the tracks. (If I thought this warranted it, I suppose some kind of cue-sheet/tracklist parser to handle track names could be devised, but I’m happy with the time savings this far.)

The New Yorker: Fact: As a result, the war was largely marketed domestically as a scare campaign, and the I.N.C. was enlisted to promote the danger posed by Saddam’s regime. Brooke said, “I sent out an all-points bulletin to our network, saying, ‘Look, guys, get me a terrorist, or someone who works with terrorists. And, if you can get stuff on W.M.D., send it!’”

The New Yorker: Fact:

As a result, the war was largely marketed domestically as a scare campaign, and the I.N.C. was enlisted to promote the danger posed by Saddam’s regime. [Francis] Brooke [US-based manager of Ahmad Chalabi’s intelligence factory] said, “I sent out an all-points bulletin to our network, saying, ‘Look, guys, get me a terrorist, or someone who works with terrorists. And, if you can get stuff on W.M.D., send it!'”

A pretty maddening article: one almost feels sorry for Chalabi for being pushed beyond his own unsavory limits. But not really. What to do about the dreamy-eyed blockheads who saw the fall of Saddam’s Iraq as their version of the Berlin Wall? Voting them out doesn’t seem enough somehow.

The New York Times > Technology > Knowing Their Politics by the Software They Use: “It may be that the populist-versus-establishment dynamic plays out as Democrat versus Republican in this election,” Mr. Weitzner said. “But the open-source movement is a populist phenomenon, enabled by the Internet, and not a partisan force in any traditional sense of politics.” The lone trait common to open-source supporters, according to Mr. Torvalds, is individualism. Politically, he said, that can manifest itself as independence from either political party. “But it also shows up as a distrust of big companies,” Mr. Torvalds wrote, “so it’s not like the individualism is just about politics.”

Interesting how much this debate spills into different areas. Recall that the file pilfering story of earlier this year was linked to improperly secured servers running the Leading Brand: it is possible to make any system unsecure, but for some reason it happens more frequently there.

And the quote “There was no pressure. We were free to use whatever software we thought worked best” about the selection of MSFT, couple with the claim that security and data privacy were key drivers doesn’t really add up. Oh, well, there’s always room for people who need to be told what to think.

Pogo was right

Inaugural Address, January 20, 1961: So let us begin anew–remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof…. Let both sides explore what problems unite us instead of belaboring those problems which divide us. Let both sides, for the first time, formulate serious and precise proposals for the inspection and control of arms–and bring the absolute power to destroy other nations under the absolute control of all nations…. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths and encourage the arts and commerce. Let both sides unite to heed in all corners of the earth the command of Isaiah–to “undo the heavy burdens …. And if a beachhead of cooperation may push back the jungle of suspicion, let both sides join in creating a new endeavor, not a new balance of power, but a new world of law, where the strong are just and the weak secure and the peace preserved.

Oliver Willis quoted all of JFK’s Inaugural Address. I thought these passages were appropriate for today’s needlessly divided times.

Inaugural Address, January 20, 1961:

So let us begin anew–remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear. But let us never fear to negotiate.

     Let both sides explore what problems unite us instead of belaboring those problems which divide us.

     Let both sides, for the first time, formulate serious and precise proposals for the inspection and control of arms–and bring the absolute power to destroy other nations under the absolute control of all nations.

     Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths and encourage the arts and commerce.

     Let both sides unite to heed in all corners of the earth the command of Isaiah–to “undo the heavy burdens . . . (and) let the oppressed go free.”

     And if a beachhead of cooperation may push back the jungle of suspicion, let both sides join in creating a new endeavor, not a new balance of power, but a new world of law, where the strong are just and the weak secure and the peace preserved.

     All this will not be finished in the first one hundred days. Nor will it be finished in the first one thousand days, nor in the life of this Administration, nor even perhaps in our lifetime on this planet. But let us begin.

LEONARD PITTS JR.: Anger stirred by Moore film is wonderful :

One of the least attractive characteristics of conservatism from that era forward has been its perpetual anger. Meaning its capacity to feel put upon, to work itself into a froth of righteous indignation, demonizing the opposition such that “liberal” becomes not a competing political philosophy but a curse word.

We have met the enemy and he is us.

HOWTO: configuring a music server

If that sounds like you, read on. The underlying protocol that makes iTunes work is the afore-mentioned daap, and most of your open source operating systems offer it in one form or another…. But to make it visible from your clients, you’ll need to advertise it using some implementation of multicast DNS, variously known as Rendezvous or ZeroConf. There are three versions in ports: Port: howl-0.9.4 Path: /usr/ports/net/howl Info: Zeroconf/Rendezvous implementation Maint: paul@aps.org B-deps: expat-1.95.7 gettext-0.13.1_1 gmake-3.80_2 libiconv-1.9.1_3 libtool-1.3.5_2 R-deps: Port: mDNSResponder-62_1 Path: /usr/ports/net/mDNSResponder Info: “Apple’s mDNSResponder” Maint: alfred@freebsd.org B-deps: expat-1.95.7 gettext-0.13.1_1 gmake-3.80_2 libiconv-1.9.1_3 R-deps: Port: mdnsd-0.7G Path: /usr/ports/dns/mdnsd Info: Advertise a service via Rendezvous Maint: daniel+mdnsd@pelleg.org B-deps: R-deps: The daapd port can run on top of an existing mDNS infrastructure that uses mDNSResponder or the components in net/howl…. [/usr/ports/net/howl]# mDNSResponder -h usage: mDNSResponder [options] Options: -h this help -v display version -d run in debug mode -i ifname run only on interface ifname -a addr run only on interface whose address is addr -f config_file load config_file nDNSResponder will only bind to one interface at this writing, so we’ll need to specify that. [/usr/ports/net/mDNSResponder]# mDNSResponder -a 192.168.2.1 (root@red.paulbeard.org)-(02:06 PM / Sun Jul 04) [/usr/ports/net/mDNSResponder]# ps auxwww | grep DNS root 87980 0.0 0.5 2280 1244 ??

This assumes:

* you’re using iTunes (or some other Digital Audio Access Protocol [daap] client).

* you’re comfortable with open source — compiling and installing packages from source.

* you want to be able to listen to your music library from a central server that might not be a Macintosh.

If that sounds like you, read on.

I have built my own, albeit modest, celestial jukebox.

screen grab of iTunes

I have copied all the music files from my iBook to my server and am running a version of Apple’s Multicast DNS daemon (aka rendezvous or zero-conf) with a freeware implementation of the iTunes server. Now I can serve up my music files without the iBook, from anywhere on my local network.

I used rsync to copy everything over and will be setting up a cron job to handle that automagically.

The last hurdle is to run all the files through hymn to make sure I can always listen to them.

I’ll write up a HOWTO presently. Coincidentally, MacWorld magazine has an article on how to build a music server, but there’s not much challenge to setting up an additional Mac and using iTunes’s Sharing. Who has an extra Mac laying around anyway?

Time to re-read this. I heard it read aloud on NPR Friday morning and, bless them, they left the very last paragraph for Bob Edwards. It’s a striking document to listen to: so reasonable and clear, but at the same time unyielding and certain (when as the last time you used or heard the phrase ‘with manly firmness?’).

The Declaration of Independence of The United States of America

When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume, among the Powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.

That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shown, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.

* He has refused his Assent to Laws, the most wholesome and necessary for the public good.

* He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, He has utterly neglected to attend to them.

* He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.

* He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their Public Records, for the sole purpose of fatiguing them into compliance with his measures.

* He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.

* He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative Powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.

* He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws of Naturalization of Foreigners; refusing to pass others to encourage their migration hither, and raising the conditions of new Appropriations of Lands.

* He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary Powers.

* He has made judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries.

* He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our People, and eat out their substance.

* He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.

* He has affected to render the Military independent of and superior to the Civil Power.

* He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended legislation:

** For quartering large bodies of armed troops among us:

** For protecting them, by a mock Trial, from Punishment for any Murders which they should commit on the Inhabitants of these States:

** For cutting off our Trade with all parts of the world:

** For imposing taxes on us without our Consent:

** For depriving us, in many cases, of the benefits of Trial by Jury:

** For transporting us beyond Seas to be tried for pretended offences:

** For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies:

** For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments:

** For suspending our own Legislatures, and declaring themselves invested with Power to legislate for us in all cases whatsoever.

* He has abdicated Government here, by declaring us out of his Protection and waging War against us.

* He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people.

* He is at this time transporting large armies of foreign mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy of the Head of a civilized nation.

* He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.

* He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.

In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince, whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free People.

Nor have We been wanting in attention to our British brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.

We, therefore, the Representatives of the United States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by the Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the Protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.
