[LAD] [LAA] Ratatouille.lv2 v0.2 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. ![Ratatouille](https://github.com/brummer10/Ratatouille.lv2/blob/main/Ratatouille.png?raw=true) Ratatouille allow to load up to two neural model files and mix there output. Those models could be [*.nam files](https://tonehunt.org/all) or [*.json or .aidax files](https://cloud.aida-x.cc/all). So you could blend from clean to crunch for example, or, go wild and mix different amp models, or mix a amp with a pedal simulation. To round up the sound it allow to load up to two Impulse Response files and mix there output as well. You could try the wildest combinations, or, be conservative and load just your single preferred IR-File. Each neural model may have a different expected Sample Rate, Ratatouille will resample the buffer to match that. On the Release Page been ready to use binaries, note please that Ratatouille.lv2-v3-v0.2-linux-x86_64.tar.xz is a fully optimized version using the x86-64-v3 optimisation, you could check if your system supports that by running the command `/usr/lib64/ld-linux-x86-64.so.2 --help 2>/dev/null | grep 'x86-64-v3 (supported'` if that return nothing, your system can't use this, in that case you should choose Ratatouille.lv2-v0.2-linux-x86_64.tar.xz Impulse Response Files will be resampled on the fly to match the session Sample Rate. To build from source, please use Ratatouille.lv2-v0.2-src.tar.xz as only that contain the needed submodules.

[LAD] Pitch estimation

by Fons Adriaensen

Hello all, Several people have asked how the pitch estimation in zita-at1 works. The basic method is to look at the autocorrelation of the signal. This is a measure of how similar a signal is to a time-shifted version of itself. It can be computed efficiently as the inverse FFT of the power spectrum. In many cases the strongest autocorrelation peak corresponds to the fundamental period. But this can easily get ambiguous as there will also be peaks at integer multiples of that period, and for strong harmonics. To avoid errors it is necessary to look also at the signal spectrum and level, and combine all that info in some way. How exactly is mostly a matter of trial and error. Which is why I need more examples. Have a look at <http://kokkinizita.linuxaudio.org/linuxaudio/pitchdet1.png> This a test of the pitch detection algorithm used in zita-at1. The X-axis is time in seconds, a new pitch estimate is made every 10.667 ms (512 samples at 48 kHz). Vertically we have autocorrelation, the Y-axis is in samples. Red is positive, blue negative. The green dots are the detected pitch period, zero means unvoiced. The blue line on top is signal level in dB. Note how this singer has a habit of letting the pitch 'droop', by up to an octave, at the end of a note. He is probably not aware of it. This happens at 28.7s, again at 30.8s, and in fact during the entire track. What should an autotuner do with this ? Turn the glide into a chromatic scale ? The real solution here would be to edit the recording, adding a fast fadeout just before the 'droop'. Even a minimal amount of reverb will hide this. The fragment from 29.7 to 30.3s is an example of a vowel with very strong harmonics which show up as the red bands below the real pitch period. In this case the 2nd and 3rd harmonic were actually about 20 dB stronger than the fundamental. This is resolved because the autocorrelation is still strongest at the fundamental pitch. The very last estimate in the next fragment (at 30.85s) is an example of where this goes wrong, the algorithm selects twice the real pitch period, assuming the first autocorrelation peak is the 2nd harmonic. This happens because there was significant energy at the subharmonic, actually leakage from another track via the headphone used by singer. The false 'voiced' detection at 30.39s is also the result of a signal leaking via the headphone. Ciao, -- FA

[LAD] Update of zita-at1

by Fons Adriaensen

Hello all, Zita-at1-0.8.1 is now available at the usual place: <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> Note: this is not (yet) the new zita-at2 that will have formant correction. Changes: - Bug fixes. - Improved pitch estimation algorithm. - Low latency mode, reduces latency to around 10 ms. Note to Robin Gareus: The new Retuner class can probably be used without changes in the x42-autotuner plugin. The logic that controls jumping forward/back while resampling has been changed. Instead of just trying to avoid reading outside the available input range, it now tries to keep the read index as close as possible to the ideal position, i.e. 'latency' samples behind the write index. That also means that for unvoiced input it will be within +/- 1.3 ms of the ideal position, so nothing special is required for this case. Ciao, -- FA

[LAD] Help with resampling algorithm

by Marco Castorina

Hi everyone, I am hoping this is the right place to post this question. I am trying to implement the resampling algorithm as described in this paper: https://ccrma.stanford.edu/~jos/resample/resample.pdf I managed to construct the h (windowed sinc) table, and I have implemented the loop. I am having a hard time to compute the eta interpolation factor and the l index index for the h table. The "fixed point" implementation of the paper is a bit confusing to me. Looking at figure 7 in the paper, I think the interpolation factor needs to be computed between the h entries instead of between the original samples. However I don't understand how to compute the starting point (h(l)). I have just started working with audio code, so I might be misunderstanding something fundamental about the paper. I have coded a prototype which is shared here: https://gist.github.com/theWatchmen/746f35c349748525b412cfd9466608ce Apologies in advance if this is not the right forum. Marco

[LAD] Ratatouille.lv2 v0.1 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. ![Ratatouille](https://github.com/brummer10/Ratatouille.lv2/blob/main/Ratatouille.png?raw=true) Ratatouille allow to load up to two neural model files and mix there output. Those models could be [*.nam files](https://tonehunt.org/all) or [*.json or .aidax files](https://cloud.aida-x.cc/all). So you could blend from clean to crunch for example, or, go wild and mix different amp models, or mix a amp with a pedal simulation. To round up the sound it allow to load up to two Impulse Response files and mix there output as well. You could try the wildest combinations, or, be conservative and load just your single preferred IR-File. On the Release Page been ready to use binaries, note please that Ratatouille.lv2-v3-v0.1-linux-x86_64.tar.xz is a fully optimized version using the x86-64-v3 optimisation, you could check if your system supports that by running the command `/usr/lib64/ld-linux-x86-64.so.2 --help 2>/dev/null | grep 'x86-64-v3 (supported'` if that return nothing, your system can't use this, in that case you should choose Ratatouille.lv2-v0.1-linux-x86_64.tar.xz To build from source, please use Ratatouille.lv2-v0.1-src.tar.xz as only that contain the needed submodules.

[LAD] [ANN] Qtractor 0.9.90 - A Spring'24 Release Candidate batch #3

by Rui Nuno Capela

Hi, twice again! Now finally making the QStuff* third batch of the blooming season... [list] [b][url=https://qtractor.org]Qtractor[/url] 0.9.90[/b] ([i]spring'24[/i] aka. v1.0.0-rc1) is released! [/list] Maybe, just maybe--no promises here whatsoever--this could be very well be the last before [i]the unthinkable[/i] 🐱? Change-log: - Prepping the unthinkable (aka. v1.0.0-rc1) - MIDI Controller mappings are now shown on floating tool-tips. - Custom color themes are now file based (*.conf); legacy still preserved ntl. - Add default GM, GS and XG standard instruments definition file. - Old generic "Portuguese" translation (pt) has been corrected to the more proper "Portuguese (Brazil)" locale (pt_BR). - Up and Down arrow-keys may now be used to change event values on the MIDI clip editor current selection (eg. note velocities). - MIDI clip editor now featuring lollipops for all kind of candy event values ;). - Make the minimum width of events on the MIDI clip editor larger, depending on screen resolution and horizontal zoom setting. - Avoid issuing equivalent MIDI track channel volume and panning via GM standard controllers (CC#7 and CC#10 resp.) to mitigate recursive or positive feedback loops. - Refined mouse-wheel control step size on the sliders of mixer strips and generic/stock plugin editor dialogs. - Fixed the build checks on whether to use old or newer style of LV2 include headers. - Introducing colored strips on the time ruler headers for loop and punch recording ranges. - Fixed an off-by-one(-pixel) mispositioning of selected events, while on the MIDI clip editor (aka piano-roll).
