[LAU] Need to determine bit depth from command line

by Kevin Cosgrove

Is there any command-line way to tell what the bit depth of a sound file is? Sox's '-e stat' doesn't say that. /usr/bin/file only gives the sample rate. Audacity, not command-line, tells me that my file in question is "Mono, 44100 Hz, 32-bit float". I'd rather not have to use Audacity on all my files to figure out which ones are 16-bit and which ones are 32-bit. I suppose I could use sox to find out how many samples, file to find out the sample rate, /bin/ls to determine the size, and then calculate the bit depth. Anyone? Thanks.... -- Kevin

Re: [LAU] Some Problems/Questions (about jack , qmidiarp and maybe other)

by Hermann Meyer

> qmidiarp has jack support but i don't know how use it to connect this > application If you use qjackctl you can connect all applications in the connectwidget. If you use jackd on the comandline you can list all ports with jack_lsp, connect ports with jack_connect and disconnect them with jack_disconnect greetings hermann

[LAU] Piano and bass

by schoappied

Hi, I'm a newbie when it comes to audio and linux... I play the guitar by myself, with the help of software like jack and jack-rack. The drums comes from Hydrogen. But where can I get the bass and the electric piano on Linux? Best regards, Dirk

[LAU] Hardware synths

by lanas

Folks, OK, Linux synths are great. And yes, if many ways they are. Although recently I got a M-Audio Prokeys88 and I swear the Warmpad sound in there does not have any equivalent in richness in what I've heard so far in Linux soft synths. If you do have an close-sounding Linux soft synth sound, let me know, I'd be very interested in hearing it. That makes me tend to believe that hardware synths sounds are still leading in quality, deepness and richness. Any other opinions ? Cheers, Al

Re: [LAU] Some Problems/Questions (about jack , qmidiarp and maybe other)

by Hermann Meyer

hi when I use vsthost and wineasio I set the Frames/Period to 2048 with a real bad latency from 85.3 msec. There for I use qjackctl with two different presets. Normaly I use dssi-vst for vsti's with a Frames/Period 128 and latency from 5.33 msec. some apps will launch jack if you start them with jacklaunch appname. I dont now your apps, maby it works. greetings hermann

[LAU] ALSA parameters

by M-.-n

Hi guys, I'm trying to get my audio driver working with ALSA but there's the issue of defining the buffer size and period that I can't seem to figure out really. I've tryed to google for some good definition of what they represent and how they should be used with respect to the asynchroneous callback but couldn't find too much that would help. Would someone care to elaborate on this ? Thanks Marc

[LAU] endless loop for practice sessions

by millward

Is there a Linux program that will run a wav file in an endless loop? I could use this to jam along with my own chord progressions or ripped song and maybe one day get good enough to play with real people. maybe.

[LAU] Fwd: searching for good guitareffects

by Juan Fabián Simón

Hi, try to search in previous posts of this list, since about one month ago (around 9-dic) someone started a thread about that, and maybe you'll find some info there. I'm recalling a little: http://gnupc.de/~zettberlin/law/patches/ams/ams-guitrack_RC1.ams (the author says it sounds like a marshall combo amp). There's a guy from the Musix project who made some jack-rack presets, you'll find some info here: http://audiores.uint8.com.ar/files/code/LADSPA_plugins/disthordian/index.php http://www.musix.org.ar/wiki/index.php/Distorsion_para_guitarra_disthordian (but sorry, it's in spanish, though maybe google can hack that ;) ) Luck! Juan.

[LAU] Seq24 and general MIDI questions

by Charles Linart

Hello, The MIDI world is new to me so forgive me if some of these questions are kind of dumb. My overall strategy is to get my beats, keys, and basslines down in Seq24 using Zyn, amSynth, and Hydrogen, then send the midi tracks to Rosegarden for addition of audio and further tweaking, then mix the whole thing down as audio in Ardour. Does that sound about right? 1) Is it possible to send a Seq24 song track-by-track to Rosegarden? How? I have been bouncing all the tracks to one audio track and mixing in additional audio tracks in Ardour, but that seems like a sub-optimal way to do it. If I could get it in Rosegarden in midi form, then I could fine-tune the midi tracks even after recording audio, right? 2) Where can I get additional instruments for Zyn? The ones that come with it out of the box are OK, and it's great that you can edit them and roll your own instruments. Right now I just want a nice natural sounding bass, and the ones that come with Zyn are not cutting it. Anybody know where I might find such a thing before I spend five hair-pulling hours making my own? 3) Can Ardour be used as a midi sequencer? Is it possible to put a midi track in Ardour or do you have to send it as audio? Many thanks in advance.
