Re: [linux-audio-dev] why is no-one responding

I have spent much time reading about potential problems and responded to all those that have had the courtesy to respond. I have also learnt and spent much time investigating problems that have nothing to do with the production of music.. simply to try and help developers iron out problems.. Pretty much everyone into linux audio at this point does that. If you look back into archives a couple of years back alot of development into inclusion of MIDI sync was added to some softwares (especially MusE) to accomodate users like myself who depend on this sync to make software compatible with real studios. BUT. In the last few weeks I have spent much time into trying to configure and compile ardour (the potentially greatest audio recording software available to us) Heh, I've been up to the same task. It seems to depend on fairly recent development tools, and upgrading to them all can mess things up. But slowly working towards it. but all my responses after I sent an opinion to the string ahem concerning Steinberg having produced (but not released) versions of their commercial softwares under our much loved platform, have been completely ignored.. except this one.. My responses have not been ignorant nor lacking in information. As I mentioned I have spent much time learning about the Linux platform and contributing when I can ... Well, position yourself with a working ardour, and then think how much time you would spend on helping others, when all that time you could be making music :) My annoyance is when it was asked of me to provdie more information and I did .. no response came.. then when I tried to resolve it myself and no further response came that's when I could only put 2 2 together and see that a response I made to the string ahem could have been related Sometimes more information does ring a bell to someone, sometimes it doesn't. That's pretty much about it from my point of view. There are many bits in cyberspace. janne (or is there? ;) cheers Allan

AUDIO_RATE_CONTROL could be useful, but might be painful for hosts to implement. I dont have any particular use for it right now. Not to mention that AUDIO_RATE_CONTROL would completely useless in JACK? You'd have a buffer-full of samples and apply frequency shift to them, which would change the length of that buffer, which you couldn't give to JACK unless you do some rebuffering. Correct me if I'm wrong. We have similar issue with ecasound's Pitch Shifter operator in connection with JACK. janne

No, I dont think so. An audio rate control is just one that has a value per sample, instead of a value per block. Its usful for things like FM frequency which can be changed very quickly. Hey, I just thought of a use for it ;) But how can it be used for tempo tapping then? janne

Tempo tapping is a way of determining the tempo of the musicians music, you tap the button in time to the music and the software then uses that to sync delays and similar effects. It doesn't do any time stetching. Ah, allright. Neat. :) janne

Well, there is module in standard lib to read and write wavs, called wave. http://www.python.org/doc/current/lib/module-wave.html To play them, I have used a module called linuxaudiodev. It's bit strange since there is no mention of it in any documentation, but it has been bundled with python for some time now, for what I know. Interface is similar to module sunaudiodev. http://www.python.org/doc/current/lib/module-sunaudiodev.html The linuxaudiodev module seems bit buggy, but is fine for basic operation. Maybe it's nice to use libsndfile for soundfile stuff. I did it before for someone who programs in Pascal. If you come up with bindings for libsndfile, I'd be very interested. For playing sound I was thinking about the pyeca thingy, but it's just an interface to ecasound, and to play a sound you first need to write it to a file. What's wrong with writing straight to alsa or oss device? janne

The source is available, though the program itself is pretty unusable for reallife purposes. :( I'm thinking of rewriting this thing on gtk2 someday. :) janne
