I want to add a silence to the end of each Mp3 file. I have about few thousand files so I cannot add them manually .
The length of the silence = the length of mp3 file + 2.
For example: If the length of mp3 file is 10 seconds, the length of silence will be 10 + 2 seconds
I used below code but it didn’t solve my problem. So can you help me to write it, please ? Thank you very much !
And if you export MP3, you’ll have a few thousand lower quality files. Audacity creates new MP3 files when it exports. You’re not really “patching” or “adjusting” the old files. This means Audacity has to go through the compression step again and that means the music quality is going to be a bad combination of old and new sound damage.
People who expect the same quality and file sizes generally are not happy. You can export each file at much higher quality and get around this problem (recommended), but the files are going to be much bigger.
Being obsessive, I only do production in WAV (Microsoft) which has no compression sound damage. Those files are huge.
There are “pure” MP3 editors that do work on the original file and have no addition damage.
I did not mention direct MP3 editors because I don’t think they will easily add silence to files, especially if nguyenguyen wants a different length of silence for each file. Those editors work on cut/copy and paste, or you could record a silent MP3 and join the silent MP3 to another MP3.
Yes, you are right. The purpose is I will repeat the sentences as soon as I listen them.
Thank you for writing the code. It worked but after processing, the length of tracks is same although the original length is different.
I imported a lot of mp3 files to Audacity at once. So for a 10 seconds MP3 you want to add 12 seconds silence, and for a 20 seconds MP3 you want to add 22 seconds silence. How to do it ?
