The media files you deliver to YouTube for music videos must conform to these specifications.
Audio Profile
Attribute | Specification |
---|---|
Codec | FLAC Linear PCM PCM audio in Eclipsa Audio file format |
Sample rate | 48kHz recommended. Higher sample rates are accepted but not required (for example, 96kHz). |
Bit depth | 24-bit recommended, 16-bit acceptable |
Channels | 2 (stereo) Up to 18 channels and up to 2 audio elements (Eclipsa Audio)
|
Although it is not recommended, YouTube accepts compressed audio. YouTube transcodes from the delivered format; audio quality is much better when transcoded from a lossless format compared to re-compressing a lossy audio format.
If you must deliver compressed audio, use these specifications:
- Codec: AAC-LC or Opus or Eclipsa Audio
- Sample Rate: 48kHz
- Bit Rate: 320kbps or higher for 2 channels (higher is always better; 256 kbps acceptable), 128kbps per channel for Eclipsa Audio
- Channels: 2 (stereo), up to 18 channels for Eclipsa Audio

Notes | Edit lists are not allowed as these cause loss of A/V sync. moov atom must be present and at the front of the file. |
