[Ardour-Users] automatable tape-recorder like playback speed?

[Ed Ward]

That is odd. I just downloaded yout tone.wav, stretched it 200%, "Resample without preserving pitch" and it works exactly as you want it. Note that Minimize time distortion must be unchecked, maybe that's where th problem comes from ?

Regards,
Ed

that's precisely what i thought, but the results are not what i'm expecting.

here's a test tone:
https://www.dropbox.com/s/aiz4k4rh0na1zbj/tone.wav?dl=0

and here's what i get at 200%:
https://www.dropbox.com/s/h35keuh01ix2gth/tone200.wav?dl=0

and here's what i get at 500%:
https://www.dropbox.com/s/yab57iwivvopf1s/tone500.wav?dl=0

i'm expecting it to pitch down as it stretches longer. am i doing
something wrong?

best,
patrick
