[ANN] Vee One Suite 0.6.3 - A sixth beta release

by Rui Nuno Capela

[UPDATE] As a micro dot release override, the current sixth beta release is out and crunching the earlier fifth to oblivion ;) Howdy, The 'Vee One Suite' of 'old-school' software instruments, aka. the 'gang of three' have bumped over another tiny notch: synthv1 [1], as one polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as one drum-kit sampler, are now being released to the masses. Again ;) There's no big audible changes, if any at all, yet this fifth beta release is rather a probable bug fix drumkv1 LV2 on Ardour. Anyway, it's all gone as follows: - Sample file drag-and-drop support has been added to the note element list widget (drumkv1 [3] only). - Main widget layout changed as much to allow sampler display and element list to expand or grow vertically as needed (samplv1 [2] and drumkv1 [3]). - Sample file path mapping has been fixed for LV2 plugin state restoration, which were preventing Ardour to reload any of the saved session or preset sample files in particular (drumkv1 [3] only). - Custom knob/dial behavior mode options are now introduced: linear and angular (aka. radial) as far to avoid abrupt changes on first mouse click (still the default behavior). - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. We're still available in dual form, as business as usual: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. Enough to tell, the Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. As always, have (lots of) fun :) **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.6.3 (sixth official beta) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Integer performance

by Will Godfrey

Just a curious thought... If you are using only small values is there really any benefit in using chars and shorts rather than just using integers everywhere and letting the compiler sort it out? Also, would bool actually have an extra cost due to masking needs? Obviously large blocks of data are a different issue! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

strategies for mixing streams of differing channel counts

by dave＠661.org

Could I get some ideas and advice on the subject of reconciling two streams with different channel layouts? Going from mono to stereo is straightforward: make a stereo stream with both channels carrying the same data. Mixing a one or two channel stream with 5.1 or 7.1 also seems fairly clear: the audio goes to the front left and right channels. Is this line of thinking solid? What I don't understand is how to reconcile 5.1 audio with 7.1? Which two of the four side and rear channels of 7.1 should receive the two rear channels of 5.1? Also, should mono streams be mapped to the center channel of 5.1/7.1? I understand that the chances of someone writing a game that would go beyond stereo are rather slim, but I'd rather not risk having someone write a game that won't run on other Z-machines, but not mine. I'm also considering extending the results of my work into a general-purpose mixer library. -- David Griffith dave(a)661.org A: Because it fouls the order in which people normally read text.

NSM launch client for debugging

by Alex Norman

I swear I saw a document once about it but now I cannot find it, I'm wondering how I can launch my NSM client app, via NSM, but also via a terminal so I can see the standard out/error? Also, being able to use GDB would be great. I have a bug somewhere in my app shutdown process [via NSM] that only seems to happen with NSM. I'd like to resolve that :) Thanks to anyone who can clue me in or point me to this doc! Alex

mixing music and sound effects using libao

by dave＠661.org

I've been playing around with libsndfile, libvorbisfile, libmodplug, and libao to provide background music and sound effects for a game engine. I have a solid handle on making one noise at a time, but I don't understand mixing. At first I thought I would have to write my own mixer and handle the channels, sample rate, and sample size issues myself. I really don't want to have to do that. Then I noticed in the libao documentation that nothing says that I cannot spawn two threads, each of which calls ao_open_live() and ao_play() on different sound files. Indeed, the docs for ao_initialize() seem to suggest this can be done with the statement that it be called in the main thread. I tried this and it works so erratically that I'm not sure libao was written with this in mind. I get these results in order of likelihood: 1) "Segmentation fault" 2) "*** glibc detected *** ./threadtest7: malloc(): memory corruption (fast): 0x0000000001bc5390 *** Bus error" 3) "*** glibc detected *** ./threadtest7: double free or corruption (out): 0x00000000018ba2e0 ***" 4) A bit of the first file, then the second file. 5) Only the second file. 6) Both files messily mixed with a zipping noise. (very rare) Is libao in fact intentionally capable of doing this? If not, what are my options for mixing music and sound effects? I really don't want to use SDL_mixer for a variety of reasons, chiefly because my program is terminal-only. Virtual beer if you can guess what the program is. -- David Griffith dave(a)661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing?

GuitarSynth

by Gerald

Hi guys, I've started/hacked a small project called GuitarSynth. It is meant as a playfield for exploring pitchdetection and synthesis for Guitar, since I'm a guitarist. You can get on Github (git clone https://github.com/geraldmwangi/GuitarSynth.git). Its really basic but its fun to play with. It take an audio signal (your guitar) extracts the fundamental pitch and drives some wavetable synths. Feel free to manipulate it, I'll be happy to grant people write access to the repo. Btw on IRC my Nick is JimsonDrift, the name of my band (see www.jimson-drift.de). Cheers Gerald
