[linux-audio-user] jackd -d alsa -d hw:0 -p512 / problem to start

by felix.news＠qodiga.com

HI! I was installed alsa + jackd, and jackd not start using this command line: # jackd -d alsa -d hw:0 -p512 And the output is an infinite lines just like the following lines... **** alsa_pcm: xrun of at least 0.019 msecs **** alsa_pcm: xrun of at least 0.051 msecs **** alsa_pcm: xrun of at least 0.016 msecs **** alsa_pcm: xrun of at least 0.015 msecs **** alsa_pcm: xrun of at least 0.020 msecs **** alsa_pcm: xrun of at least 0.014 msecs **** alsa_pcm: xrun of at least 0.025 msecs [...] But jackd is 'running' but not usable, because 'ardour' abort saying: 'jackd not present' What can I do? thanks a lot for your help, Felix

by André Alves Pereira

Hi! First of all sorry by my very bad english... Now my problem. My right mouse button doesn't work with Ardour... I'm using Ardour/GTK 0.406.1 running with libardour 0.694.0 with Slackware 9.1 low latency kernel 2.4.22. I had this problem before and I resolve removing the ~/.ardour/ directory, but now this doesn't work... Anybody knows why? Thanks for any help! André Magoo

[linux-audio-user] recent hydrogen / jack / ardour

by Paul Winkler

hi all, i've got recent cvs of ardour and jack and really wanna get a drum machine plugged into it. so, hydrogen. I got libhydrogen from cvs built fine, but hydrogen appears to require qt 3.2 and gentoo only seems to provider 3.1.2. D'OH! I think i can get 3.2 if i update world, maybe... which takes forever... ah the self-inflicted pain of gentoo :-) anybody know exactly what I need to compile hydrogen cvs? do i really need the whole thing of qt 3.2? -- Paul Winkler http://www.slinkp.com Look!

[linux-audio-user] question about libalsaplayer's functionality (and its possible incorporation in my app)

by Ivica Bukvic

Hi all, I've tried contacting the maintainer of the project (Andy), but he never bothered to reply, so now I am taking this question to all of you out there that might have had exposure to this interesting library. Does anyone know what is the current status of the whole project anyhow? Any help on this matter is greatly appreciated! When answering any of the given questions, please include the question in your reply. Thank you very much! So here's the excerpt from the letter: I've recently decided to incorporate libalsaplayer-like functionality the upcoming version of my app RTMix. However, with having a particular feature in mind I am wondering whether libalsaplayer provides that and if not, whether you'd be willing to add it (or let me add it, although that might get messy since I am not too familiar with the inner workings of the lib). So, here it goes: Apart from all the wonderful features libalsaplayer offers, I am looking for some additional ones: I would like to be able to indefinitely loop specific "ranges" of a particular soundfile (i.e. 2.2secs-4.12secs or whatever). 1. Is it possible to do this and have music continually loop even if one changes the direction of playing so that when the alsaplayer runs out of the looping material in each direction that it just jumps back onto the other end of the loop and contiues on (kind of like a ring-buffer)? 2. Is it also possible to do this kind of looping on the whole soundfile (the gui version of alsaplayer always stops if I let it play 'til the end or the beginning, depending in which direction I am going). 3. Is it possible to define loop points by addressing a particular sample number rather than giving time in seconds? 4. How stable is alsaplayer when looping really small chunks of sound (i.e. like 5 sample loop)? 5. Is alsaplayer capable of ramping such loop points by attenuating let's say ending 20 samples (it would be cool if this number could be user-selectable) and then ramping up the beginning 20 samples in order to alleviate the "pop" that happens when looping a sound where waveforms at the beginning and the end do not align? 6. If the feature in question 5 does not exist is there a way to control output level of a player on a per-sample basis via callback so that one can implement that outside of the lib? 7. If neither 5 or 6 are possible, would you be willing to implement such functionality (i.e. a toggle_ramp( bool ); and set_ramp_length( int ); callbacks or something similar. I would greatly appreciate your feedback on this matter as that will greatly assist me in determining how to go about implementing such functionality in my app. Thank you very much! Looking forward to hearing from you. Sincerely, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico P.S. How do you implement reading of a sound faster and slower than it sounds in such a gradual fashion? Do you adjust the sampling rate of the DSP and if so does that affect other streams coming from the libalsaplayer, or is this something that is sound-specific (and if so, how)?

[linux-audio-user] ALSA on Redhat - besides the Planet

by Frank Barknecht

Hallo, just a short information question: Is it true, that Redhat does not provide any ALSA packages themselves so people who want to run some of the many ALSA applications on Redhat will have to use third-party rpm's like Fernando's or from freshrpms.net? Is this really true? If yes, does someone know what RH's plans are regarding ALSA on kernel 2.6? ciao -- Frank Barknecht _ ______footils.org__

RE: [linux-audio-user] ... like an old vinyl

by Reuben Martin

First: Using an equalizer, kill all frequencies below ~600 and above ~2k. Use a graphic EQ for this. (The two values are just examples, you can play with both frequencies to get the desired sound you're looking for.) Second: get a recording of the inside blank track that comes after the last song of a noisy record. Loop this noise and mix it over top of the song once you've done the band pass filter from step one. -Reuben -----Original Message----- From: Michal Seta [mailto:mis@creazone.32k.org] Sent: Wednesday, October 22, 2003 8:32 PM To: A list for linux audio users Subject: [linux-audio-user] ... like an old vinyl Hi all, Does anyone know if it's possible, under linux, to turn a good quality audio recording into a file that sounds like an old vinyl record.
