YouTube is infamous for compressing video and audio files upon upload. If you've spent weeks mastering your track, the last thing you want is for it to sound muffled online. So, what is the best audio format for YouTube upload?
Understanding YouTube's Compression
When you upload a video, YouTube transcodes the audio stream into formats like AAC and Opus. YouTube's official recommendation for audio is a stereo AAC-LC track at 384 kbps. Because YouTube automatically compresses your audio, you must provide them with the highest quality source file possible to avoid "generation loss" (compressing an already compressed file).
WAV and FLAC: The Lossless Kings
The absolute best formats to use are uncompressed files, mainly WAV (.wav) or FLAC (.flac). These formats contain 100% of your original audio data.
If you upload an MP3 (which is lossy), and YouTube compresses it again, you get a muddy sound. By uploading a WAV file within an MP4 container, YouTube only compresses the audio once.
How to get a WAV file onto YouTube?
Since you can't upload a raw WAV file to YouTube directly, you must wrap it in a video container like MP4. You can use our free WAV to video converter to do exactly this.
- It accepts lossless WAV and FLAC files.
- It renders a high-quality video track synced to your audio.
- It exports as an MP4 that YouTube's algorithm loves.
