Listing lowest and highest frequencies in a track?

by Bearcat M. Şándor

Folks, Is there a Linux program out there that i can throw a wave file at that will tell me what the lowest and highest frequencies are in it, where they are and at what dB they occur? I was listening to some dubstep today and wondering how low it really went. I would bet that most of the "bassy" music i have doesn't even go below 30 hz. Thanks, Bearcat

[ANN] WhySynth DSSI softsynth 20120903 release

by Sean Bolton

I'm pleased to announce the 20120903 release of WhySynth, a DSSI softsynth plugin. New since my last release announcement: * One new oscillator mode (Wavecycle Chorus) and four new filter modes (resonz, high-pass and band-reject, with thanks to Luke Andrew). * Some new patches. * An icon for desktop use. * A bug fix for an ugly click that would occur when using portamento in monophonic mode. * WhySynth development is now hosted on Github. Find WhySynth here: http://smbolton.com/whysynth.html More information on the DSSI plugin standard, available hosts and plugins can be found here: http://dssi.sourceforge.net/ WhySynth is written and copyright (c) 2012 by Sean Bolton, under the GNU General Public License, version 2.

Re: [LAD] Kontakt sampler format (Chicken Systems Translator)

by Tom's Lists

I know this is somewhat already covered in this discussion, but this is straight from the head of Chicken Systems (a friend of mine). I asked him if there was any way beyond converting the samples (which Translator can do just fine) to get the Kontakt samples into Linux, and this was his reply: "All the scripting is lost, there's nothing really to convert it to since no other platform is as intelligent. Of course, EastWest uses Python and I forgot what MachFive 3 uses, but I'm not sure how demanded such a conversion is." So, until NI ports Kontakt to Linux, or someone else makes an equivalent or better sampler for Linux, we'll have to stick with some form of Windows. Unless I've missed it, has anyone gotten it to work with Wine, or through Windows in VirtualBox? I'm building a machine that will have most versions of Windows as VirtualBoxes, just to experiment with it, & to get away from Windows, albeit slowly, but this isn't my DAW, just a strong Linux (Fedora 17) box. -Tom Dyrnwyn Studios & Workshops Blomkest, MN

Pianoteq VST - point of information

by Edward Diehl

I wanted to mention that Pianoteq does provide a linux VST which does work in Ardour and Qtractor. However, the default version provides 5 output channels which Ardour does not seem to like (because it expects stereo output). However, if you append "_2chan" to the plugin library name (e.g. Pianoteq.so to Pianoteq_2chan.so) , the plugin will output only 2 channels and work happily in Ardour.

CC-by-sa licensed samples/instrument plugins

by Nils

As you may know from the other sampling thread here on this list I have written several emails to sample developers over the last two days and suggested CC-By-Sa as sampling license. Clearly the intention of sample developers, they all write it in their currenct licenses, is that the resulting music is not part of the samples license. e.g. it is not considered a derived work. But for Creative Commons ShareAlike? Is music a derived work from samples under cc-by-sa? If yes I made a dumb error which could have negative impact on further talk with those developers since I was obviously talking about things I didn't know enough about. Also if yes: Is there even a pre-packaged license that allows: -Music or other resulting works are not derived works and the following conditions do not apply to the music itself. -Sharing the sample packages is allowed -Editing, Repackaging (sf2->sfz) etc. is allowed -Selling the sample package itself is allowed or not (two different flavours) Nils

Possible to run jackd on Android?

by Bill Gribble

For a few years I have used an Atom UMPC as my "mobile development terminal", allowing me to build and run code at much lower performance than I would expect from a "real" system but good enough for working on new bits of code and finding performance bottlenecks :) I am migrating over to a Nexus 7 with a Debian chroot environment and tightvnc for display. This is working great for most things. The last bit is to be able to run jackd so I can actually test audio parts of the programs I work on the most. I don't care about latency, or even xruns. This isn't for production use. I just want to be able to exercise the jack client library, make connections, and hopefully get SOME audio output. The current problem I am having is that sys V shared mem API is not supported. $ jackd -d alsa jackdmp 1.9.9 Copyright 2001-2005 Paul Davis and others. Copyright 2004-2012 Grame. jackdmp comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK semaphore error: semget creation (Function not implemented) jack_shm_lock_registry fails... No access to shm registry Failed to open server Has anybody done anything like what I'm working toward? Any workarounds for missing shm API? Thanks. Bill Gribble

Trying to understand mixer in ALSA API

by Alexandre

Hi Kinda new to linux audio and still a bit new to dev generally and I'm trying to understand the basis of linux audio. By that, I mean the ALSA API : I would like to use the PCM interface and the mixer interface to mix 2 sounds and understand the real meaning of a mixer used in the Audio Architectures. For now I understood that the mixer interface uses the High level control interface (hcontrol), which uses basic kernel modules. I was wondering if anyone had some docs or examples of a program that uses the mixer interface ? Thanks -- Alex

Re: [LAD] Plugin 1/oct frequency controls (AMS/MCP/VCO)

by Jeff McClintock

> I think the most reasonable standard for an absolute 1/oct > frequency unit is 0.0 = 440Hz My modular plugins use a reference of 440Hz. Also parameters are ranged between 0.0 - 10.0 but can exceed that if need be. (in a modular synth, everything needs to interoperate). So for frequency 5.0 is 440Hz (Middle-A). i.e. the middle of the range - 5.0, is the standard 'middle' key. Great idea though. Octaves are far more universal than western semitones, yet trivial to convert between. 440Hz is a good choice. Best Regards, Jeff

[ot] A little help with fourier-transformations

by Julien Claassen

Hello everyone! I have something not realted to Linux. It's mainly how to read a few things. Anyone knowledgeable about fourier-transformation in general here, who might wish to help me? Background is a university exam, that I have to take, but only having had the script and not having found the right information anywhere else, I'd like to know, how to read/speak a few things mainly. Thank you for being with me so far.
