[linux-audio-user] Sweep 0.5.9 -- Scrubby Speex!

by Conrad Parker

Sweep 0.5.9 Development Release ------------------------------- Sweep is an audio editor and live playback tool for GNU/Linux, BSD and compatible systems. It supports many music and voice formats including WAV, AIFF, Ogg Vorbis, Speex and MP3, with multichannel editing and LADSPA effects plugins. Inside lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. This development release is available as a source tarball at: http://prdownloads.sourceforge.net/sweep/sweep-0.5.9.tar.gz?download Sweep now supports Speex, a special purpose speech codec designed for efficient Voice over IP (VoIP) and file-based compression. Speex is free, open and unpatented; more information is available at http://www.speex.org/. This release also includes improved handling of the main volume and pitch controls, contributed by Zenaan Harkness. Screenshots: http://www.metadecks.org/software/sweep/screenshots/ Audio demos: http://www.metadecks.org/software/sweep/demos.html Sweep is designed to be intuitive and to give you full control. It includes almost everything you would expect in a sample editor, and then some: * precise, vinyl like scrubbing * looped, reverse, and pitch-controlled playback * playback mixing of unlimited independent tracks * looped and reverse recording * internationalisation * multichannel and 32 bit floating point PCM file support * support for Ogg Vorbis, MP3 and Speex compressed audio files * LADSPA 1.1 effects support * multiple views, discontinuous selections * easy keybindings, mouse wheel zooming * unlimited undo/redo with fully revertible edit history * multithreaded background processing * shaded peak/mean waveform rendering, multiple colour schemes Sweep is Free Software, available under the GNU General Public License. More information is available at: http://www.metadecks.org/software/sweep/ Thanks to Pixar Animation Studios and CSIRO Australia for supporting the development of this project. enjoy :) Conrad.

RE: [linux-audio-user] changing speed without changing pitch

Thanks Luis, I'll give it a try. And I'll check out the csound list too.

RE: [linux-audio-user] changing speed without changing pitch

by Stuart Allie

Hi, I *finally* got around to trying the csound method of changing the speed of an audio file without changing the pitch, but it didn't work for me :( I used the following "orc" file: > sr = 44100 > kr = 4410 > ksmps = 10 > nchnls = 1 > > instr 1 > kfreqscale = 1 > ispecwp = 0 > ktime line 1, p3, 0 > apvl pvoc ktime, kfreqscale, "file.pvc", ispecwp > out apvl > endin and then the "sco" file: > i1 0 12 > e with a 6 second sample, so this should double the audio to 12 seconds. I did the PV analysis like this: > csound -U pvanal -n 1024 -w 4 file.wav file.pvc and then ran csound via: > csound -W -R -d file.orc file.sco -o slow.wav and then I waited for a little while :) When csound was done, the ourput file was, well, interesting... Basically the input file was 6 seconds of single-note guitar playing, and the output was a weird (though not unpleasant :) whooshing-sweeping-phasing sound for 2 seconds, then a faint LFO-type sound to the end of the file. No sign of the original clip, slowed or otherwise. Can anybody out there tell me what I (or csound :) did wrong? Thanks in advance, Stuart

[linux-audio-user] Evolution UC16 problems, modules.conf for usb-midi and usb-audio together

by m

hi all thanks for your help with compiling alsa, i've now got both usb-audio and usb-midi compiled... but i'm having problems getting midi running. the results of modprobe snd-usb-midi is a load of unresolved symbols...

[linux-audio-user] RE: [music-dsp] linux and midi

by Joachim Backhaus

> What about using midi-thru boxes? they don't add latency to > the midi signal, > they just 'amplify' and 'split'. If you run 14 MIDI devices through one MIDI Port using MIDI Thru Boxes you get a worse timing compared to using a multiple Output Interfaces like the Steinberg Midex 8 oder the Midiman Midisport 8x8. But I don't know if there is a 8x8 Interface with Linux drivers. All of them implement a feature to reduce latency and I think that's a problem for the driver developers because the companies don't want to show the specifications for that in public.

[linux-audio-user] problem converting mp3 to wav

by Howard Sanner

I just searched the archives on this and the suggestions there didn't help. I'm trying to convert some mp3 files into wav files. First I tried having Audacity export a wav file. Then I tried loading the mp3 into Broadcast 2000 and having it render it to a wav. Finally I tried the suggestion in the archives of mpg123 -w filename.wav filename.mp3. In each case, when I tried to burn a CD from the resulting wav file, cdrecord reports "inappropriate audio coding in [filename]." I'm using Eroaster 2.0.10 as a front end to cdrecord. Audacity and Broadcast 2000 both load all these wav files and play them just fine. Anybody know what's going on here? Thanks. Howard Sanner flagstad(a)mindspring.com

[linux-audio-user] problem converting mp3 to wav

by Howard Sanner

Apparently my subscription to the list got dropped. I guess that's why things have seemed so quiet lately in Linux audio land. I just searched the archives on this and the suggestions there didn't help. I'm trying to convert some mp3 files into wav files. First I tried having Audacity export a wav file. Then I tried loading the mp3 into Broadcast 2000 and having it render it to a wav. Finally I tried the suggestion in the archives of mpg123 -w filename.wav filename.mp3.

[linux-audio-user] mpg123 and mpg321 + alsa output distorts

by Olivier

Hi all, If I use mpg123 -o oss it plays fine, but I can only use my first soundcard. If I use mpg123 -o alsa09 it plays the same volume, but the sound is distorted. mpg321 has the same problem. Programs like aplay do not have the problem, so it's not for all alsa software. what do mpg123 and mpg321 have in common? and what makes them distort when using the alsa output instead of oss-emulation? the system is a AthlonXP2000+ with Asus on-board cmipci and a Hoontech ymfpci card. Both cards have the same problem with mpg123 and mpg321 and both not with aplay. anybody an idea? thanks, Olivier

[linux-audio-user] FreqTweak 0.4.4 released

by Jesse Chappell

New in FreqTweak 0.4.4: * Now deactivates processing while switching FFT sizes. This should prevent JACK from kicking you out here. * Added ability to reconnect to JACK with a different basename, or just reconnect period if we are kicked out (I/O tab). * Control-Alt left mouse draws arbitrary lines between initial click and current cursor. Also smoothed regular drawing. * More configure checks to ensure compiling against the float version of FFTW. http://freqtweak.sourceforge.net jlc
