jack_capture ============ jack_capture is a program for recording soundfiles with jack. It's default operation is to capture whatever sound is going out to your speakers into a file, but it can do a number of other operations as well. Normal URL: http://www.notam02.no/arkiv/src/?M=D Note that the above link doesn't seem to currently work because of something which seems to be www upgrade at Notam. But this link does seem to work for now: http://old.notam02.no/arkiv/src/?M=D 0.9.10 -> 0.9.17: ----------------- *Made sure the process thread won't continue sending data when jack_capture is told to quit. This led to a race conditions when recording too many channels at once (which was 256 channels on my machine). *Added the jack_capture_gui script, based on code by Svend-Erik Kjær Madsen's. *Replaced sh by bash to make it work in ubuntu. *Fixed exact port name match and gen_setformat. Thanks to Gabriel J.L. Beckers for reporting the bugs. *Increased the time the console meter is displayed in red from 50ms to 2000ms. (when the recorded jack value is equal to or higher than 1.0.) *Added the -dBr argument to specify reference level when using the console dB meter. *Added the -mr argument to specify reference level when using the meterbridge meter. *Added peak indicators to the console meter. Code to do so taken from meterbridge by Steve Harris. *Updated --help and README with the new options. *Added option "-mt" to change meterbridge type. Current valid options are vu (default), ppm, dpm, jf or sco. It's not necesarry to specify "-mb" if using "-mt". *Added option "-dB" to get a dB meter for the console meter. *Added examples how to record ogg and mp3 files using the -ws option. *Decreased default buffersize from 60 to 20 seconds. (I even had trouble provocing underruns using a minimal 0.05 seconds long buffer, so 60 seconds was obviously overkill) *Fixed message and error printing to stderr when vu meter is running.

Guitars are made from wood, and especially with cheap instruments there can be huge differences between instruments of the same brand/type. You have to play, hear and feel it yourself to judge. A friend of mine recently got a very nice cheap telecaster copy, from a series of ten in the shop it was the only good one, and he got it even cheaper because some kids had made scratches to the surface when trying them out...

tablature support in lilyond

by rosea

Hi, There is a discussion about more tablature-notation functions in Lilypond, like bend, slides, pull off etc. Are you a guitar, bass or other string player, and maybe a software developer too? Maybe you can offer you knowledge to lilypond and help develop these tablature features! Or maybe you like to see such features in lilypond and would give your support and let the devs of lilypond know that you also like to see those tablature features! If so, subsribe to the lilypond-user mailinglist and give your support. Roos

Okay, but I'm also thinking about the HD cache and the cache between the OS and the disk. I don't know how it works exactly though, but I thought that maybe it didn't write to disk as often if the cache is constantly filled with zeros. > Is that enough back-up for my "bombastically spilled out" argumentation? Sure, much better argumentation. > A double (or float) to transfer to disk is still a double (float) to transfer > to disk regardless wether the value is 0, close to zero or something close to > INFINITY... Yes, but no doubles or 64 bits are involved in this process, only 32 bit floats.

I just tried recorded 128 channels of 32bit/44100hz at once, without problem. And my machine is 5 years old 2Gz barebone, using only a single PATA ide disk. This was using jack_capture, and only recording silence (ie. non-connected jack ports). Maybe the silence makes a difference.(?) 256 channels did not work very well though.

ffado and Motu Traveler

by Raphaël Bollen

Hi everyone, I'm trying to get my Motu Traveler to work on Linux but... The ffado mixer is working correctly, I can tune the settings of the Traveler but when I start jackd, it crashes 2 seconds after. I've tried different settings frames/period etc. but I always get the same behaviour. Does someone have suggestions of what I could try next? -- Raphaël.

Laptop Sound Adapter for Ripping my Vinyl Album Collection

by Kevin Cosgrove

I'm gonna bite the bullet and rip all my music to play it around the house via my computers. I've got really good music gear for the job in my home studio. But, my turntable and record collection is just about as far from there in my house as is possible. I don't want to move either set of gear. Instead I want to get sound adapter for a laptop I've got and do the ripping at the location where my turntable resides now. My laptop has USB. I don't know if it's USB1 or USB2. But, I can get a cardslot to USB adapter for cheap, if need be. I'm planning to store my digital music losslessly, in either FLAC or WAVPACK. I want the music to sound as good after being ripped as it did on my pretty good home stereo via the turntable. I know I need at least 2 channels, but I'd go with 4 channels on the adapter, if it didn't cost me double. What would you recommend as a sound adapter for this job, and why? Thanks.... -- Kevin

Re: [LAU] Host 128.173.232.121 is unreachable via http or smtp ports

by Ivica Ico Bukvic

Thanks Ron for the info, we are already aware of this issue and are working on it as fast as we can. As unlikely as it sounds, it appears we've had a major thunderstorm that has knocked out several buildings on campus, including the building hosting our server. Unfortunately, I've been out of the country and unaware of this occurrence until it was brought to my attention yesterday. Let me say that this is a very unusual and very much unexpected occurrence. That being said, based on this unfortunate development we will look to invest into better UPS asap to minimize any potential downtime in the future. As of 4:58PM the server should be back up and running.
