I’m a new user and an old german man. Excuse please my bad english because it’s very old school english.
I have now on opensuse tumbleweed the new Audacity and want to change mp3 audios from 440 hz to 432 hz.
Is it right that I must activate the effect timescale for it?
In Germany it gives an tutorial for this hz changing with the effect timescale.
But when I activate this effect I can’t find it in the menu and can’t make an new macro.
When now I look in the menu to the macros the effect is deactivate again.
How can I solve this problem or how can I change the hz of an audio anyway.
Very much thanks for your answer.
I took VLC to load a mp3-audio and had a look to the codec information by many of my audios.
It stands at the sampling rate: 44100 hz or sometimes in other audios at 48000 hz, but no 44000 hz.
Then I have calculated:
44000 - 1.818% = 43200;
44100 - 2,039% = 43200,
44800 - 3,571% = 43200;
Does it give a shell command for many mp3-audio for that I can get a result in a file about the following:
for x ... do
<audiofilename.mp3> with <samplingrate> hz
There’s an app (available in the repositories for most Linux distributions) called “MediaInfo”.
If you open an MP3 in MediaInfo it will show you the sample rate and a lot of other information about the file format.
There is also an online version of MediaInfo here: https://mediaarea.net/MediaInfoOnline
