Re: [linux-audio-dev] impulse convolution LADSPA plugin

by Stefan Turner

Hi Steve, thanks for the reply. I will definitely look into using DSSI, looks like it could be good once as supported as LADSPA is (I'd never even heard of it before your post, although that's probably just me). Is it intended as an eventual LADSPA replacement? I never really saw the need to divide plugins into 'instruments' and 'effects', and it seems like DSSI can do both.

Otherwise I would always get the GUI. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

[linux-audio-dev] [ANN] One more delay meter

by Fons Adriaensen

Hi all, The round-trip delay meter mentioned recently on jackit-devel is now available at <http://users.skynet.be/solaris/linuxaudio> The tarball is just 2.6k, so you won't waste much bandwidth :-) Jdelay is a JACK client that measures the delay between its output and input, assuming the channel in between has a linear phase response (i.e. delay is independent of frequency). If you connect it to your soundcard and make a loopback from out to in, it will give you the round-trip latency of your system. Precision is around 1/1000 of a sample if you have a decent sound card. Even in adverse conditions (S/N ratio reduced to 0 dB by adding white noise) it will still measure the delay to within 1/10 of a sample. Enjoy ! -- FA

[linux-audio-dev] deblocking snd_seq_event_input()

by Fons Adriaensen

Hello, Is there a simple (i.e. simpler than getting the pollfd and using them) to force snd_seq_event_input() in blocking mode to return, so the the calling thread can close the handle and cleanup ? Neither snd_seq_close() nor snd_seq_nonblock() seem to have any effect. -- FA

[linux-audio-dev] Waveform

by Fisher, Michael R

Hi, I'm extremely new to audio programming. I have a million questions, but the one burning my brain now is how do I get a program written with the qt widget library to display an audio waveform. Also, any links to good documentation for audio programming would be good. Thanks Mike Fisher

[linux-audio-dev] Gungirl Sequencer Version 0.3.0

by Richard Spindler

Hi, Gungirl Sequencer Version 0.3.0 is ready, and it comes with an impressive set of new features: - Automations, Fade-in, Fade-Out - Unlimited Undo - Sample Stretching and Trimming - Unlimited Number of Tracks - Zip-Packages of Songs - Looping About ggseq: It's a simple Audio-Sequencer designed for arranging small Sound-Loops, as available on CD from various Producers. It's not a general Purpose Sound Editor, it has no support for large audiofiles. It doesn't do MIDI. It's a fun toy, for people new to electronic music-making. It's available from the Gungirl Sequencer Homepage at: http://ggseq.sourceforge.net/ There is a source tarball that requires the following dependencies: - wxGTK 2.4.x or later - libsndfile 1.0.0 or later - libsamplerate 0.0.15 or later There is a statically linked binary release that should run on most recent Version of the GNU/Linux OS, provided GTK+ is installed. And there is a win32 Installer. Have fun -Richard Spindler <richard.spindler AT gmail.com>
