Robert, i've got an AI-3 and am very happy with it. i use it with a hammerfall light. the AI-3 doesn't have a lot of bells and whistles, but i just need a basic converter with high aural quality. and, like you, i didn't want to go overboard on the $$$. if your needs are similar, i think you'd like the AI-3. patrick > I'm looking to purchase a brand spankin' new HDSP 9652 Hammerfall > and I need an external AD/DA to go along with it. I've looked at the AI3, which makes $$$ sense and i've looked at the ADI 8 Pro line, which makes features sense (huh?). Which converter would you all recommend? Is there anything good/bad i should know about the AI3/ADI 8 Pro DS? > > Thanks a lot in advance! > > -Robert C

[linux-audio-user] WARNING: padding up to secsize.

by Howard Sanner

My usual way of creating a CD is to record to the hard disk, edit in Broadcast 2000, "render list," and burn the resulting WAV files to a CD. Every time I do this, without exception, cdrecord prints out this message after each track. I notice that when burning WAV files people have sent to me that they've created under other operating systems (i.e., not just Windoze), cdrecord doesn't give that message. I'd like to understand what's going on, and if it has any ramifications I should be worried about. Thanks. Howard Sanner flagstad(a)mindspring.com

[linux-audio-user] iiwusynth and ALSA midi?

by Paul Winkler

hi, i've got alsa from cvs (/proc/asound/version says 0.9.0rc6) and iiwusynth from cvs (reported as 0.2.4 at startup). I also tried iiwusynth 0.2.2 from tarball, with the same result. What's happening: I've got a raw midi input device at /dev/snd/midiC1D0 (/dev/midi01). I've compiled iiwusynth OK (without readline) and it can run fine with alsa's oss midi emulation: $ iiwusynth -a alsa -m oss -M /dev/midi01 ... and it responds to my keyboard just great. Try to use ALSA and I get no joy: $ iiwusynth -a alsa -m alsa -M /dev/amidi1 ~/Unshared/Sounds/soundfonts/drums/arap.SF2 iiwusynth: warning: Couldn't set high priority scheduling for the audio output iiwusynth: warning: Failed to pin the sample data to RAM; swapping is possible. ALSA lib rawmidi.c:280:(snd_rawmidi_open_noupdate) Unknown RawMidi /dev/amidi1 It doesn't seem to matter what I use for the -M argument... any ideas? Is current iiwusynth broken wrt. current ALSA? -- Paul Winkler http://www.slinkp.com "Welcome to Muppet Labs, where the future is made - today!"

[linux-audio-user] freqtweak on debian

by Paul Winkler

Anybody know exactly which wxWindows packages are needed to compile freqtweak 0.4.5 on debian (testing / unstable)? I'm now testing freqtweak from cvs to see if i get the same errors... ./configure seems fine, and i got past the fftw requirement (needed sfftw-dev), but now I'm getting nasty compile errors in the wxwin stuff... like: $ make make all-recursive make[1]: Entering directory `/home/pw/Downloads/Apps/Audio/freqtweak-0.4.5' Making all in src make[2]: Entering directory `/home/pw/Downloads/Apps/Audio/freqtweak-0.4.5/src' c++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/local/include -I/usr/lib/wx/include/base-2.2 -D_REENTRANT -DNEWWX -I/usr/local/include -g -Wall -O3 -fomit-frame-pointer -fstrength-reduce -funroll-loops -fmove-all-movables -ffast-math -mcpu=i686 -march=i686 -c FTapp.cpp In file included from /usr/include/wx/laywin.h:4, from FTmainwin.hpp:27, from FTapp.cpp:45: /usr/include/wx/generic/laywin.h:83: parse error before `&' /usr/include/wx/generic/laywin.h:84: syntax error before `(' /usr/include/wx/generic/laywin.h:86: semicolon missing after declaration of `wxQueryLayoutInfoEvent' (many following errors snipped) -- Paul Winkler http://www.slinkp.com "Welcome to Muppet Labs, where the future is made - today!"

I've started to ask questions on the gentoo-user alias about how best to deal with cvs ebuilds. Once there there are some answers i'll put together a webpage for the files. I considered going down the /opt path ;-) but it just isn't the gentoo way! j.

[linux-audio-user] AD/DA Converters

by linuxrob＠dod.net

Hey, I'm looking to purchase a brand spankin' new HDSP 9652 Hammerfall and I need an external AD/DA to go along with it. I've looked at the AI3, which makes $$$ sense and i've looked at the ADI 8 Pro line, which makes features sense (huh?). Which converter would you all recommend? Is there anything good/bad i should know about the AI3/ADI 8 Pro DS? Thanks a lot in advance! -Robert C

[linux-audio-user] Gentoo users?

by Jon Ellis

Hi, Yesterday i ended up created an ebuild to build jack from cvs - ardour needed v0.41 and gentoo is still using the 0.34 release. Updating jack broke alsaplayer (v0.99.72 is the latest in portage and the support for jack v0.4+ is in 0.99.73 :-) ) and it looks like another cvs build is in order... How are others coping with this stuff? Is anyone interested in setting up somewhere to share ebuilds, working together on getting them into the official portage? j. -- - I don't want knowledge, I want certainty. - David Bowie

[linux-audio-user] possible problems with rc6 aplay

by patrick reardon

hi everyone: i'm running on a PIII with kernel 2.4.18 and Alsa 0.9.0rc6 and a Hammerfall 9636 card. Alsa has been working fine for the last year, or so it seems. recently a scsi CD burner was installed. i have some recordings of live performances made with "arecord", version 0.9.0beta8a. they play back just fine, but when i tried to burn them to CD, they were low by about 2 to 3 half steps. Joerg Shilling suggested that Alsa was writing the wrong headers. so i upgraded to rc6 and on the first try on each of the old WAV files, "aplay" also played them too slowly. however, on subsequent runs, everything was fine again. i don't understand this behaviour at all. someone on LAU suggested that since it was too low by about 2-3 half steps, data was being recorded at 48000 but Alsa thought it was at 44100. info in /proc/asound/hammerfall/rme9652: ------------snip------------- . . Latency: 4096 samples (2 periods of 16384 bytes) Hardware pointer (frames): 0 Passthru: no Clock mode: autosync Pref. sync source: ADAT1 IEC958 input: Coaxial IEC958 output: Coaxial only IEC958 quality: Consumer IEC958 emphasis: off IEC958 Dolby: off IEC958 sample rate: error flag set ADAT Sample rate: 44100Hz . . ---------snip----------------- for months up until about an hour ago the ADAT sample rate read 48000. in that hour i changed my .asoundrc from -----------snip--------------- pcm.hammerfall { #"hammerfall" is the alias for "snd-rme9652" in /etc/modules.conf type hw card0 } ctl.hammerfall { type hw card0 } -----------snip--------------- to the following -----------snip--------------- pcm.rme9652 { #changed from "hammerfall" to "rme9652" on 12.15.2002 type hw card 0 } ctl.rme9652 { #same as above comment type hw card 0 } ---------snip----------------- after the .asoundrc change i recorded a fresh WAV and burned it to CD but with the same problem -- too slow. also, with the new .asoundrc, version rc6 plays WAV's recorded with the old .asoundrc and version rc6 a little too fast. i'm at a loss for new ideas to debug this. can anyone enlighten me about this, or does anyone know where i can download some reference WAV files (for example, a middle C tone) to check whether the burning problem might involve Alsa or whether it's something else in my setup? any pointers would be greatly appreciated. tia, patrick

[linux-audio-user] Zalman cooling

by Jon Ellis

There was some talk of silent cooling earlier in the week. It reminded that i need to quiet my new pentium 4 box. Does anyone have any experience with Zalman? In particular, this: http://www.zalman.co.kr/english/product/cnps5700d.htm Seems they have "silent" power supplies... Comments? j. -- - I don't want knowledge, I want certainty. - David Bowie
