'man qsort' is your friend. Step one: The compare() function, that you supply to qsort, should open two files and compare for equality until EOF (in which case they are equal) or return when and unequalty is found. The array you are sorting holds the paths to all of your candidate mp3s, which you have found by recursively traversing your partition(s) Step two: All the paths to the mp3s are sorted so that paths with equal content are next to each other. Go thru them once, using the same comparison function as before. For each equal pair delete the lowest ordered file. For each unequal pair move the lowest ordered file to a place where you would like to keep your mp3 collection. /jens > any way I can avoid listening to hundreds of files would be most > appreciated. > > any suggestions? > > Thanks > Aaron >

Re: [linux-audio-dev] Audigy 2 ZS Notebook PCMCIA card.

by Peter Zubaj

> What are my chances of getting it to work under Linux? Zero My opinions: For me looks like this will be based on same chip as Audigy 2 Value - this is not emu10k2 - this is new chip (maybe emu10k2 based, but new). If someone buy Audigy 2 ZS Notebook then it can confirm this (if this is true or not). Why I think so, because creative don't make extra chip for only one card. Only change is reverse engineering windows drivers. I think better is invest time to something other as this.

[linux-audio-dev] mp3 mess help

by Aaron

HI all, I have set of mp3's that I have been working with over the last few years. They have been backed up, renamed moved to different directories. most of them are not tagged. after a few crashes/loss of a hard disk etc. I am now trying to restore my work. I have a full partition with them in it but it is obvious most of them are there multiple times with different non discriptive names..ouch:( Is there a way I can searh the mp3 to find which are the same/different using the actual mp3 binary data?? any way I can avoid listening to hundreds of files would be most appreciated. any suggestions? Thanks Aaron

by Susan R. Cragin

This sound card is supposed to be pretty good, and portable. It just came out. What are my chances of getting it to work under Linux? Audigy 2 ZS Notebook PCMCIA card. Thanks. Susan R.

[linux-audio-dev] [ANN] Snd-ls V0.9.1.1 and Sono V0.2

by Kjetil Svalastog Matheussen

http://www.notam02.no/arkiv/src/ Snd-ls 0.9.1.1 changes: 0.9.1 -> 0.9.1.1: -Fixed Append File edit-menu option. -Workaround for trouble with ladspa default settings. Sono 0.2 changes: Some very few small changes to make it compile with linux again. Used some code from the port for Redhat 6 in 2000 by Roger Klaveness. Snd-ls ------- Snd-ls is a distribution of the sound editor Snd. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. SONO - MAKES A PRESENTABLE SCORE FROM YOUR ELECTROACOUSTIC PIECE ---------------------------------------------------------------- This little program takes a soundfile of any length and writes a Postscript file with a 'score', including sonogram and oscillogram. This can be printed directly on your laser. Sono was written for SGI computers. --

[linux-audio-dev] [ANNOUNCE] SRC support for XMMS OSS output plugin

by Jussi Laako

Hi, I have made a patch which adds support for samplerate conversion to XMMS's OSS output plugin. Samplerate conversion is done using Erik de Castro Lopo's libsamplerate aka Secret Rabbit Code. Why? Because there are soundcards which support only single samplerate in hardware (usually 48 kHz). To get best possible sound quality out of these, you'll need high quality samplerate conversion when playing 44.1 kHz files/streams. All comments on this are welcome. Patch is available from: http://www.sonarnerd.net/linux/xmms-rabbit.patch -- Jussi Laako <jussi.laako(a)pp.inet.fi>

[linux-audio-dev] Speech recognition

by Susan R. Cragin

Hello. I am a not-very-technical person trying to get some opinions to pass along to our group. We are trying to get speech recognition working on Linux and want to test everything using the same USB sound pod and the best microphone, provided that the equipment is widely available to the general public. Right now the microphone of choice seems to be the Sennheiser MD 431 II. For USB Sound Pod we understand that many of them do not run properly with Linux, and of those that do, some do not transmit enough subtlety to capture small variations in speech. Any and all suggestions or comments would be appreciated. Susan Susan R. Cragin, Director Open-Source Speech Recognition Initiative susancragin(a)earthlink.net http://www.ossri.org http://harvee.org/mailman/listinfo/ossri susancragin(a)earthlink.net

[linux-audio-dev] [ANN] liblo 0.13

by Steve Harris

liblo is an implementation of the Open Sound Control[1] protocol for POSIX systems. It is written in ANSI C and released under the GNU General Public Licence. It is designed to make developing OSC applictions as easy as possible. http://plugin.org.uk/liblo/ This release adds Mac OSX compatibility fixes from Taybin Rutkin, a memory leak fix from Jesse Chappell and methods and examples to allow server polling from exisitng threads from Sean Bolton. Some legacy compatobility code has been removed, but this should not affect anyone. Documentation has been updated to reflect the changes.

Re: [linux-audio-dev] Re: killer app idea

by Dave Griffiths

Going slightly off topic, an idea I'd like to try is a hexagonal drum pattern sequencer. I got the idea from this: http://www.soundonsound.com/sos/apr04/images/autechremax2.l.jpg I have no idea how it actually works, but from that patch I got thinking that you could get multiple loops from the same pattern by moving time in different directions across a (non rectangular) tesselated grid. If you see what I mean!?? I'm going to hack together a little script to do this, when/if I have time, but feel free to take this idea further...

by Juhana Sadeharju

>From: Aaron <aamehl(a)actcom.net.il> > >1. Basically a front end to lilypond which will work >more like a audio program. I remember something like that has been discussed somewhere earlier. Well, if the rectangle on the track editor is made with audio editor, it is displayed as waveform or as spectogram. If the rectangle on the track is made with midi editor, it is displayed as matrix. If the rectangle is made with X editor, it is displayed as X. When one zooms in to these displays, they might become editable. (Waveform display usually does.) Maybe this should be mentioned in this context (before anyone patents all these ideas): a rectangle may have different reprentations and thus different display styles. E.g., if the original data is audio, then the another representation could be sequence data (midi?) generated with, e.g., wave-to-midi. When the audio is edited, the other representation is changed automatically (possibly using lazy-evaluation). If the original is the sequence, then audio is just renderation of the sequence (sort of freeze feature). I wanted to write about this multiple-representations because in graphics, Silicon Graphics (Wavefront-Alias, Maya) has a patent on using multiple reprentations. User-friendly for user-editing, faster for rendering. I invented exactly that basic idea in high school 10 years before they! So, if there are further ideas, lets hear them all now before the ideas are patented.
