![]() ![]() If you zoom in on the waveform in Praat, you can select what you think is one period, and Praat will tell you both the duration of that period and how many of those period fit into one second. Also, try to identify the pitch in the wave file and make the calculations manually to confirm it.This does not have to be computed manually. You can experiment with the "noise reduction" setting in the "Reduce noise" window.Ĥ- I suggest you to test with your ears if the f0 is accurate with a keyboard for example. Depending on the software forever.Indeed, the sound may actually become less intelligible and less natural. It may be useful for movie production where maybe the resulting sound does not artificial with noise removal, but you always loose something in the audio. Nevertheless you loose high frequencies for for example.Besides going to "some software", you can also just use "Reduce noise" under Filter when you select a Sound in Praat.ģ- Noise removal always remove certain data from speech data, so I would not recommend that. No need to go to Audacity for that one either.Ģ- If the noise is only at certain frequency, say 6000, you can remove the noise with some software that have noise removal and the sound will sound clean. If instead you find the standard silence threshold of 3 percent too high, then you just lower it to 0.01 or so in the "Advanced pitch settings" under Pitch in the sound window. This doesn't influence the visibility of pitch, though, as I just said. If by normalizing the audio you mean multiplying it by some constant factor, then you don't have to go to Audacity, because Praat has commands for this under Modify, including "Scale peak". A part of the sound that you consider voiced is analysed as "silent" only if the amplitude of that part of the sound is below, say, 3 percent of the maximum amplitude. Praat does not care about the overall level. In order, to see pitch, I had to normalize the audio using Audacity.Some of these things are not true. I happened to me yesterday with a recording of my student. Op, om 08:10 heeft alexsandro_meireles via groups.io het volgende geschreven:ġ- if the recording is too low, Praat cannot generate pitch. ![]()
