[linux-audio-user] The dreaded .ape

by S. Massy

Hi, Anyone knows whether there is any way to decode .ape files in Linux? I believe there is an xmms plugin lying around somewhere: any other decoder one might use? Thanks, S.M.

[linux-audio-user] Lumpy sound from a Soundblaster mp3+

by william henry roberts

A question from a newbie: I have a Soundbalster mp3+ usb sound card attached to my HP laptop running Redhat 9. It works great and I was amazed at how easy it was to get it going, worth a look for those after a USB sound card. However I have discovered problems when I record with it. Any recording I make is full of little skips, more skips if I record at higher qualities. I am using sox to both play and record. Any insights? Will

[linux-audio-user] Greetings from a newcomer(and something about shaketracker and gcc 3.2=)

by alderamin＠jippii.fi

Hello! Like the subject line says, I'm a newcomer, this is my first post on this list. So, hiyall =) Also, forgive my faulty English. (and the long rant, possibly even a bit OT too) When I found Shaketracker I was bouncing with the joy, until I tried to compile it. There aren't so many good music apps for linux and especially not too many tracker-like midi apps. I really like the tracker UI but I can't seem to find good 'classical' instruments(samples) for trackers. I have good midi instruments, but I dearly hate the input system almost all midi composing tools have adopted. So Shaketracker was what I had been looking for some time... and like I said, I couldn't get it to compile. At this point I didn't try to fix it myself, because usually with some googling you'll find out someone else has made a patch or there is actually a new version of the software which compiles etc. So, after googling, I had only found other people who had the same problems. I took a hammer and began fixing it myself with not-so-optimistic feelings. I got it working though, it was mostly namespace problems, some code changes here and there. I still gives warnings but compiles and runs(works) on my RedHat 9.0 system. So, someone still struggling with this problem, I have got a patch for you to try out =) - SampoV __ Ota itsellesi luotettava kotimainen email http://www.jippii.fi/ Tutustu samalla netin parhaaseen pelipaikkaan JIPPIIGAMESIIN.

[linux-audio-user] noise from soundcard

by Joshua Haberman

This is a little off-topic, but I hope you don't mind. I get quite a lot of noise from my soundcard. There is a pulsing that sounds something like a very fast morse code at a consistent pitch, and it's unacceptably loud. I notice variations in this noise based on how I move my mouse. At first I thought this was just because of my shoddy 5-year-old Soundblaster Live, but I have a new Audiophile 2496 and it does the same thing. Today I tried removing the stereo mini plug from my soundcard and touching it to the metal on my case. The sound was nearly identical. >From the little that I know about electronics, I conclude that the problem is voltage fluctuations in the metal of the case. Does this mean my case needs to be grounded somehow? What can I do to fix this problem? Josh

Sometimes when electrical outlets are wired, the ground connection isn't actually grounded and is useless. Sometimes power strips have a little light on it to show if it is actually grounded or not. Also, cheap power conditioners can help alot. (Rack Rider for instance)

I wonder why folk want to live within labels. Labels are so you can organize you cd collection. Not that I've not adopted a few myself. It's just that... take country, for instance... why do artists tend to drag that whole thing out rather than taking it upon themselves to deviate from it as much as the folk who made "country" {the core folk} managed to deviate from what was around at the time? Why are they content with simply mimicking the earlier or defining aspects of whatever movement? Do they actually think that country or metal or punk or whatever else came about that way? Back to your point... I like lots of different movements... I may borrow from lots of different movements... no way in hell I'd ever create within or for a specific movement.

I don't really have a problem with Bush... He's not done all that badly given what he's had to deal with. I think he's gotten a bit hawkish of late. I wouldn't rule out voting for him.

[linux-audio-user] OSS Emulation and .asoundrc files

by Mark Knecht

Hi, I'm not clear if this is possible at all. Can someone explain how I might make a .asoundrc file that would only allow applications that use OSS emulation to access specific playback channels. Currently any app that uses OSS emulation drives all 26 playback channels on my HDSP 9652. This causes two problems: 1) Since my hardware mixes the 26 inputs into 2 stereo output pairs, the output over-drives if the 26 inputs are loud. 2) Any app using OSS emulation blocks all other apps using OSS emulation. What would be great, if it can be done, is to create a sort of 'virtual OSS' device in .asoundrc that only drove specific Alsa playback channels, so that Mozilla, for instance, talked to a specific entry in .asoundrc and ended up only driving two specific playback channels, like playback_22 and playback_23. I would be willing to live with a requirement that all OSS apps had to use the same sampling rate or blocking would occur. That's not an issue for me. Is anything like this possible with Alsa? Thanks, Mark

[linux-audio-user] Make a .GIG out of the MIS piano Was: Re: Copyrights on samples

by Benno Senoner

The free sampled piano is here: http://theremin.music.uiowa.edu/MIS.html (click on the Piano link) It is quite large, abot 1.5GB (each note sampled individually in 3 velocities: pp, mf, ff). I do not know how good the quality of this piano is, Steve Harris hacked together a small player and posted some mp3s that were rendered from a MIDI file driving his application. To me it does not sound that great, perhaps you need to tune the velocity splits to make it sound well. Anyway this sampleset is really large and can hardly fit into RAM. SF2 was not created to be streamed from disk thus I suggest the following. We of the linuxsampler team made significant progress in .GIG playback thanks to the wonderful work done by Christian S. He actually wrote libgig which is able to parse and load .GIG file supporting all the articulation stuff (layering, key/velocity switching, dimensions etc). see our new webpage (thanks Marek ;-) ) http://www.linuxsampler.org (the new code is not online yet, because Christian and I are fixing bugs and optimizing the streaming). I cannot make forecasts when full GIG playback will be done, but shortly (1-2 weeks) we will release a version that can play back the samples (without effects, and envelopes for now). This means we will soon be able to play the MIS piano directly streamed from disk using LinuxSampler. So the advice to Atti and others is: One of you should use a Windows app which allows you to create .GIG files (with GigaStudio being the natural choice), download the MIS samples, tune volume, velocity-splits, trim samples (some samples have a bit of silence at the beginning etc) and make a .GIG file out of it. After the piano sounds good in GigaStudio you should post it online. That way as soon as LinuxSampler is ready (the piano sample does not require filters, envelopes etc) we can release a truly free Grandpiano in software (samples + player). To compare how well the MIS piano .GIG you will create ,sounds I suggest you to use this page: http://www.af.lu.se/~fogwall/piano.html On that page you find a classical music midi file Fantaisie-Impromptu (Chopin) and the corresponding audio clips rendered with various digital pianos, hardware expanders and software samples (including VST The Grand, various multi-Gigabyte piano samples for Gigasampler etc). Not sure about the quality we can achieve, for example the MIS piano does not include pedal down samples. IANAPP (I am not a piano player) so I do not know if this is a big disadvantage that makes it sound unprofessional. Worth a try anyway. What do you think ? cheers, Benno >> * sample the grandpiano of the latest Roland/Korg/Yamaha electric >piano >> * give the sample away >> * package it (sf2) and put it on my web site >> > if you are prepared to go through all the pain of trimming and looping > zillions of samples, why not do the real thing ? > there is a raw set of steinway grand samples floating around on the net > somewhere (was even announced to this list iirc), and i think it's even > an anechoic recording. > the license was something along the lines of "free for the taking".
