Is it possible to integrate soundtouch.js into WIX? I hope so! I want to create the html elements in the WIX editor and change the soundtouch-js code to WIX-Velo. Can anyone help me with this? I would be very happy!

I have the latest version. I am using the files from the tar release (https://www.surina.net/soundtouch/soundtouch-2.3.2.tar.gz) I did more tests and here are the result. Initial data : 120 BPM Guitar starting at 7,894034 bar Converting to following BPM, the Guitar start is offset as follow : Tempo (bpm) Event (bar) Delta 60 7,8188 -0,0752 75 7,8521 -0,0419 90 7,8414 -0,0526 105 7,8588 -0,0353 120 7,8940 0,0000 135 7,8880 -0,0060 150 7,8801 -0,0139 165 7,9195 0,0254 180 7,9086 0,0146 Maybe, I am...

I try to use Soundtouch to change the tempo of a recording without introducing a time offset. As a matter of fact, I noticed that the output is always shift left (sounds starts before what is expected). For example, if a recording is at tempo 120 Bpm and the sounds starts at sample 1000, I would expect that the sound would start at sample 2000 if I change the tempo to 60 Bpm but it´s not the case, the sound starts before that. Is it possible to avoid that? If not, is it possible to know the exact...

Hello everyone. I use Visual studio 2022 and juce framewok to develop sound processing applications in C++. I've downloaded Sountouch dll library: https://www.surina.net/soundtouch/soundtouch_dll-2.1.1.zip I added the directory which contains .lib files to additional library directories in linker settings. Also I located the dll file in the same directory with my application exe. The header file is included too in my code. I get unresolved external error for soundtouch functions. I couldn't realize...

I just wanted to say 'thank you very, very much', because after hours of work and trying a lot of audio libraries for several purposes Soundtouch was the only one that just worked out of the box! I'm on Windows 10 for this project (I love linux though), using Android Studio 3.5.2. The ReadMe for Windows says you need to download the NDK and install it with Cygwin, but in Android Studio, you can do it like this (do mind, I haven't tested it on other/fresh computers, I'm just eager to share the unexpected...

Hi. I process file "sinus_pcm-signed_16bit.wav" (further as "Input file") with default parameters (-tempo=0 -pitch=0 -rate=0) using SoundStretch 2.1.1 for Windows [15-Nov-2018]. SoundStrecth creates file "sinus_pcm-signed_16bit_tempo0_pitch0" (further as "Output file"). Output file should not differ from Input file because default parameters were used. But as i can see it is not. For example: Input file consists of parts of the same data (sinus with different frequencies). Size of every part is 529200...

The settings were correct, but I did find the issue. Since I'm using JUCE, it doesn't seem to allow me to add paths and/or link libraries through Xcode, I have to do it through JUCE's Projucer in order for it to be implemented in the project in Xcode. Now it compiles properly.

Hello, The "Undefined symbols" error by the linker suggests that C++ compiler uses the .h files but linker can't find object files compiled from the corresponding .cpp files. Accordingly verify that the .cpp files are surely included in your project, that they surely get compiled, and that linker path settings are correct so that linker can find the required obj files.

Hello, I'm currently on macOS High Sierra 10.13.6, and using Xcode 9.4.1. I'm also using JUCE for this. I seem to not entirely understand how to implement SoundTouch into my own project. I have all the source files that I need from SoundTouch in my project folder and I did #include "SoundTouch.h" into one of my .h files in my project where it will be used.

Meanwhile, I switched to the beat detection of aubio - a really great tool to analyze audio. But soundtouch is still my one and only tool to change tempo and pitch. No other brings results like your customized WSOLA algorithm. Nice to hear, that you moved to git. Unfortunately, Sourceforge is not what it was some year ago.

Added a note that SoundTouch source codes moved to git repository

Yes: I committed BPM algorithm improvements just a moment ago. I have not thoroughly tested these with different music types yet, but these work much better than before. I have moved the source codes from svn to git, the new git repository is here: https://gitlab.com/soundtouch/soundtouch

Hi Olli, I have written a commercial application that uses your SoundTouch library. In LGPL terms, I think the P/Invoke approach I used counts as "a work that uses the library". Unfortunately LGPL instructions on what I need to do is not exactly clear. How visible does the LGPL need to be? For example, would it be acceptable for me to only include files named SoundTouch.dll and SoundTouch.license in my zip files? Under LGPL, do I display your copyright and license alongside mine in the executable's...

This is a reply to an older post. The current BPM routine doesn't give good enough BPM estimate in some cases, I have some BPM algorithm improvements in my desk drawer, will need to integrate those to SoundTouch release.
-
Check these: How does your code know how many input samples it gets? If it has different amount of input samples than it expects, it surely stutters Casting between types. Your code has quite many castings between data type and it's difficult to say from the source code if they are correct.

SoundTouch works by chopping sound into shortish sequences, and mixing these back together. Due to this approach the sound may get echoing wah-wah artifact particularly when slowing down the tempo a lot, or increasing the pitch a lot. If artifact is present even at small tempo/pitch adjustments, then it's about something else, like incorrect samplerate, or other processing parameters. Surveying Martin's parameter set above, setting the SETTINGS_AA_FILTER_LENGTH parameter to 1 seems peculiar: The...

I got the issues covered by using float buffer now the issue is stutter. I will look for another solution for this.

Hi I am using SoundTouch with QT to do some pitch shifting. And currently using SOUNDTOUCH_INTEGER_SAMPLES instead of the float samples. Please see the code below const unsigned char *ptr = reinterpret_cast<const unsigned char*>(data.data()); SAMPLETYPE sampleBuffer[BUFF_SIZE]; int nSamples = BUFF_SIZE / nChannels; for(int i=0; i<BUFF_SIZE; i++){ sampleBuffer[i] = reinterpret_cast<SAMPLETYPE>(ptr); ptr+=sampleSize; } soundTouch.putSamples(&sampleBuffer[0], nSamples); do { SAMPLETYPE outputSamples[BUFF_SIZE*2];...

Martin Loga posted a comment on discussion Help
I have the same problem. In my case it's more like a stuttering. I configured soundTouch like this setSettings(SETTINGS_USE_AA_FILTER, 1); setSettings(SETTINGS_AA_FILTER_LENGHT, 1); setSettings(SETTINGS_USE_QUICKSEEK, 0); setSettings(SETTINGS_SEQUENCE_MS, 40); setSettings(SETTINGS_SEEKWINDOW_MS, 15); setSettings(SETTINGS_OVERLAP_MS, 8); and I doubled the sample rate and halved the pitch

Hello Olli. please notice that you don't need to feed all data in a single large buffer, you can also call the bpm->putSamples several times in sequence with time feeding a smaller block of samples to the bpm algorithm. OK but there is something I am not sure. Does bpm_getBpm() freed the previous data added by bpm-putSamples ? This because I do not see a bpm_clear. Or must the instance be deleted by bpm_destroyInstance' before to do a new BPM search (and so recreate a new bpm_createInstance())? I...

Hello Olli. Could be possible to dream about a Music decoder? With this the final goal would be to decode the notes used in a buffer. I know that it is utopic, but could it be possible to begin with the begining and have a kind of GetFrequency(the_buffer). to retreive the main frequency of a buffer (for example a string of a guitar.to tune it). Maybe SounTouch uses some dsp and window to retreive the frequency and could create a new GetFrequency() method. I realize that it could be doable for a single...

Hello Olli. Your SoundTouch library is one of my favorite. Lot of years ago I was super-impressed by the Bass audio library because of his BassFX plugin. That BassFX could make stretching (= changing the tempo of a song, keeping the original tuning). The dream of every musician (in my vinyl time, you may change the tempo but the tuning changed too --> must detune the guitar --> the hell ). Later I noted that all the code that BassFX used for stretching was your SoundTouch code. I am really happy...
