Hello all,

Quick question:

I just wondered if there was short time Fourier transform function that someone has written that would be suitable for the 6713 DSK ?

Many thanks,

Jack

    Hi Jack,

    Thanks for your post.

    I believe, there are some FFT examples demonstrates the use of the C67x DSPLIB FFT filtering capabilities

     and performance benchmarks referred in the below E2E thread:

    http://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/115/t/265955.aspx

    Also, there are sample code available in the above thread (0815.fft_example_sp.c & 5238.fft_example_sp_spra947a.c)

    Thanks & regards,
    Sivaraj K

    Sivaraj, many thanks for the reply,

    I was rather hoping there was a library function for the STFT, I am currently using a similar FFT function in a loop-like manner to go through my time domain signal and calculate the STFT. It's a bit temperamental so I was hoping there was something a little bit more robust.

    Thanks,
    Jack
