Introducing the New Dashboard on Repost by SoundCloud
May 30, 2022
If you’re having trouble with the quality of your uploads on SoundCloud, we have some suggestions to improve your experience. Sometimes, when listening to your track you may find that the sound quality does not meet your expectations. The problem isn’t your speakers or software: it could be a result of the uploading process.
We recommend you upload in a lossless format like WAV, FLAC, AIFF, or ALAC. We also support a large variety of lossy formats, including OGG, MP2, MP3, AAC, AMR, and WMA. The maximum file size is 4GB. If your file exceeds these criteria, please split it into separate uploads. For a full list of support codecs and containers, check our supported file formats.
We want to preserve your work, that’s why we recommend you upload uncompressed or lossless audio files to ensure that the transcoding process results in the best possible quality. As part of that process, we resample and transcode it to a high-performance codec. These codecs are highly optimized, but they can increase peak levels, which can cause clipping. We recommend that you leave between -0.5 and -1 dBFS of headroom to prevent artifacts like clipping during transcoding. Make sure to check the resulting stream in the rare case where more headroom is required.
When you make your track downloadable, this allows your listeners to download your track in the same format you uploaded it in, without any additional transcoding.
If you upload a stereo file in a lossless format like WAV, FLAC, AIFF, or ALAC, we’ll transcode it in a high-quality format optimized for music streaming like AAC 256 kbps. If you can, the bit depth and sample rate should be 16 bit and 48 kHz respectively.
If you have the originals, but you uploaded your tracks in a lossy format before, you can re-upload your tracks by following these steps.
