Are you going to modify my podcast's audio files?

When you upload your audio files to Transistor, we won't change your ID3 tags or downsample your audio.

If your file doesn't have ID3 tags, we will add them for you when you upload. If they aren't already present, we add ID3 tags for:

Episode Title
Podcast Title
Author
Publishing Year
Episode Number

If you upload an AAC or WAV file, we will convert it to MP3 for you (after you upload).

If your MP3 file includes chapter markers, we will keep them in the file for your listeners.

Our recommendation: audio files should be encoded at 44100 Hz and around 128 kb/s quality. For loudness, we recommend -16 LUFS.
