export to mp3

hi, i ma trying to export the sound file i have created to mp3 so i can listen on ipod. the file converts but when i playback the is no sound, any thought pls

Does the file play on the computer?

What happens when you re-open the MP3 in Audacity? Do you see the waveform? Does it play?

What’s the file size and (expected) playing time? Do you know what quality or bitrate settings you used?

If you are recording with a USB device, see: https://manual.audacityteam.org/man/faq_playback.html#usb
