Ninja Step 2012

by Dan MacDonald

Hi LAU! I've been a frequent poster to this list over the last few years yet I've never had any Linux-made productions online that I wanted to admit to before now but this one has already been well received by the few who have heard it already so I thought I should share it here so I can at least get some feedback off Julian - will he like my synth snare or not?? ;) Ninja Step 2012 is a remake of 'Ninja Step' which was the background music from the factory stage of Super / Revenge of Shinobi on the Megadrive (or Genesis as it was known in Northern America). ROS was one of the first games released from the Megadrive and it also had some of the best music on a 16-bit video game, thanks to the stellar chip tune skills of Yuzo Koshiro who most famously went on to do the music for the Streets of Rage series - another definite highlight in video game music history. I created this track with qtractor, Aspect, samplv1 and mhwaveedit. Its the first track I have created with Aspect and samplv1 and my second qtractor production - my first qtractor track used Noisemaker and Highlife instead. I created this mainly to see how well Aspect and samplv1 work (together, under qtractor) and they've passed with flying colours - well after Rui fixed an issue in samplv1. I didn't experience any real issues with Aspect creating this track except for the minor inconvenience of its window disappearing when I open one of its drop-downs but this is a qtractor issue as it doesn't happen under Carla. I'm very impressed with Aspect for a few reasons. Its kinda sad I've ended up throwing in the all-FLOSS DAW towel and buying a commercial synth although I think its worth every penny and I'm happy to pay to show my thanks to Loomer for being 1 of 2 (out of a potential 1000's) commercial plugin devs to support Linux. You get free upgrades and support for life, its full GUI fits on my netbook display and with about 15 instances of it (as in Ninja Step 2012) I get no xruns and less than 15% CPU use on my 3/4 year old 2Ghz core2 duo laptop and thats just running the stock Deb Wheezy kernel. Sadly there is no real FLOSS (or even non-free actually) alternative to Aspect yet although I'm confident that won't be the case forever. Thanks for listening! http://soundcloud.com/danmacdonald PS I reported the fact that Soundcloud doesn't work with GNASH recently and its devs are working on fixing that now https://savannah.gnu.org/bugs/?37008

get BPM from MP3 files?

by Jeff Sandys

Is there any program that will guess the Beats Per Minute of an MP3 file? Bonus points if it can write the value to the ipod BPM attribute or ID3 tag. -- Jeff

Borderlands Synth - RTAudio issue

by michael noble

I'm trying to run the synth that was featured on CDM. (https://ccrma.stanford.edu/~carlsonc/256a/Borderlands/#Guide). Unfortunately I can't find any support details on the website. I think it is the same problem that crops up with RTAudio, but it only runs at 44100 here. If I try to run at 48000 then I get the following error: RtApiJack::probeDeviceOpen: the requested sample rate (44100) is different than the JACK server rate (48000). RtApi:: a stream is not open! RtApiJack::closeStream(): no open stream to close! I was wondering if anyone knew an immediate solution to this issue. michael

(Auto-)Tune a wave file

by Nils Gey

Hello, I have samples here, single-note recordings from instruments, that need tuning. I am looking for a permanent/destructive way to do that. I can do the batch processing part myself so I only need a hint how to do it for one file. The file(s) are nearly correctly tuned and I already know what it is supposed to be, if that helps. Example: I have a file resembling the midi a4 which should be 440hz, but maybe it is 430 to 450. So the optimal input would be: "Tune this file to a4" where the analysis of the actual frequency is done by a program. Quality is the top priority. Since the tuning is very fine I don't care if the speed of the recording changes or not. I take what sounds best. So, any command line tool available for that? If not a GUI tool is fine as well.

zretune app added to libzita-resampler

by Fons Adriaensen

Hello all, Release 1.2.0 of libzita-resampler now include the 'zretune' app which resamples an audio file by (the inverse of) a ratio given in cents. The output file will have the same nominal sample rate as the input. The effect is to change the pitch AND the lenght of the original file. For small pitch changes (+/- a semitone) the modified length of a sample probably won't matter much. For example zretune --cent 50 input.wav output.wav will result in a file that sounds a quarter tone higher and is about 1.5 percent shorter. Enjoy ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.

[OT] How to deactivate left clic on a touch screen

by Carlos sanchiavedraz

Dear all. Anybody knows how to deactivate the left clic event when you put your finger on a touch screen? The thing is that I still haven't found a way to achieve a proper behaviour of the touch screen on my UMPC as a live music station. Every time I put my finger on it it triggers a left clic, so when I try to move the cursor it moves some window or clic on a button when I want not. I've been experimenting with drivers and even modifying xorg.conf but didn't get to make the screen work as it should. And still don't know how at least deactivate this behaviour, so I can move the mouse with my finger (with no clic at all) and then use one of the two hardware buttons (left and right clic assigned) when needed. I mentioned this in context on a previous mail. Maybe it's not trivial and I should ask Xorg list or something else. Just in case, I ask to you dear folks. Cheers. -- Carlos sanchiavedraz * Musix GNU+Linux http://www.musix.es

Re: [LAU] Google Map of linux audio users (To: Scott (Rock Inc))

Scott, I'm so sorry, I managed by accident to remove your mark when I added myself on the map. I hope you see this (or if anyone here know how to contact Scott) message and that I haven't made to much trouble for you. Again: Sorry!
