I just uploaded and my track is distorted.Sometimes our transcoding system can create audio artifacts, as we transcode all tracks to 128 kbps mp3 for streaming playback.
We recommend uploading a lossless or high-quality lossy file to reduce these artifacts to a minimum, but unfortunately there's not much we can do for the handful of individual tracks that are still affected.
As a workaround, you can make your track downloadable. This allows your listeners to download your track in the exact format that you uploaded, without any transcoding.
To make your track downloadable, please go to the track's edit page (through the pencil icon underneath the waveform).
In the 'Permissions' tab, please click to make downloads enabled like this and click Save:
