Choose MP3 Output up to 320 kbps

Compare available audio with a studio-quality MP3 option up to 320 kbps; a higher bitrate changes file size, not detail in the original.

What 320 kb/s means for a YouTube audio conversion

YTMetadata inspects the available audio formats for the selected video and offers native audio choices alongside MP3 when available. A native M4A/AAC or Opus stream avoids a second lossy encode and is usually the more efficient archival choice if your software supports it. MP3 remains useful for legacy players and workflows that require that extension. Compare both codec and bitrate, not just the file size, and remember that the original recording, mastering, and source encode set the actual fidelity ceiling.

The 320 kb/s figure describes an MP3 encoder's output rate, not a promise that the source contains 320 kb/s of original audio information. YouTube commonly serves audio as Opus near 160 kb/s or AAC near 128 kb/s, although codecs and bitrates vary by video. Re-encoding a compressed source into a 320 kb/s MP3 can increase file size and meet a device's format preference, but it cannot recreate detail already discarded by the source. Constant bitrate (CBR) keeps a fixed rate; variable bitrate (VBR) allocates data according to audio complexity.

Frequently asked questions

How does 320 kb/s CBR differ from VBR MP3?

YouTube audio often uses Opus near 160 kb/s or AAC around 128–256 kb/s. CBR keeps a fixed MP3 bitrate, while VBR allocates more data to complex passages; neither setting restores detail missing from the source.

Should I keep the native M4A or Opus stream instead?

If your player supports the source codec, a native M4A/AAC or Opus file avoids an additional lossy MP3 encode and is often smaller at comparable perceived quality.

Why is a 320 kb/s MP3 file larger than the source audio?

A higher encoded bitrate stores more output data per second. It can improve compatibility with MP3-only devices, but the larger file does not mean the original recording had that much audio detail.

Does selecting 320 kb/s restore quality to a 160 kb/s Opus source?

No. YouTube source audio is often around 160 kb/s for Opus or 128–256 kb/s for AAC, though exact streams vary. Encoding it as a 320 kb/s MP3 creates a larger output but cannot restore detail removed by source compression.
