SymbTr to wave format

[Sajjad Abdoli]

Hi folks,

Apologize for any possible cross-posting!

Actually, I want to convert the SymbTr dataset from mu2 format to .wav files. The quarter-tones of Turkish music should be preserved. It is possible to convert the files of dataset by Mus2 software one by one. I wonder if there is a faster way to convert the whole of the dataset to wav format with preserving the quarter-tones of Turkish music.

All the best,

Sajjad Abdoli

Hi,

Mus2 doesn’t have any way of converting all of SymbTr to .wav files. The SymbTr repository (https://github.com/MTG/SymbTr) contains MIDI files for all the scores that should reproduce the pitches accurately with pitch bends. You can try exporting these MIDI files to .wav in other audio software that can do batch exports. An alternative would be to contact the authors of SymbTr to see if they have another solution.

Hello Sajjad,

 

As a simple solution, the SymbTr to WAV Matlab code below may be useful for you:

% symbtr2wav_example

fileName             = 'ussak--ornek-oz--semai----ra.txt';

sampleRate       = 44100;

write                     = 1;

[fid, msg]            = fopen(fileName, 'r', 'n');

[SymbTr, ~, ~]   = tblread(fileName, '\t');

FRQ                       = 440*2.^(SymbTr(:,4)/53-69/12);

SEC                        = SymbTr(:, 8)/1000;

AMP                     = SymbTr(:, 10)/100;

Y                             = [];

for i=1:size(FRQ)

                k             = SEC(i)*sampleRate;

                N            = [1:k];

                ENV       = 4*AMP(i).*(N*k-N.*N)/k^2;

                T             = ENV.*sin(2*pi*(FRQ(i)/sampleRate).*N);

                Y             = [Y ENV.*sin(2*pi*(FRQ(i)/sampleRate).*N)];

                soundsc(T, sampleRate);

end

wavwrite(Y, sampleRate, 16, [fileName '.wav']);
