I’m using Audacity 2.3.3 on Windows 64-bit.
I’m managing an mp3 audio, these are the informations:
Codec: MPEG Audio Layer 3(0x55) - Decoder FFmpeg interno(mp3float)
Sampling rate:: 48000
Bitrate: 0 ->16 bit/Sampling
Channels: 1 ->2 Channels
Bitrate: 128 kbps
It regards a speech, just an audio with somebody who is talking.
I need to reduce the speed of talking, keeping the pitch.
I’ve tried both “change Tempo” and “Sliding Time” under the Effects menu, setting a negative percentage value.
For the “Change Tempo” effect I’ve also checked the option for a higher quality.
The result is ok. It works as expected.
But the final voice of the audio is a bit “robotic” and less natural respect the original one.
I’m asking if exist a plugin or another tool or technique which is able to give a better result, closer to the original audio quality.
Thanks a lot.
