FSD50K: An open dataset of human-labeled sound events

This is a mirror of the FSD50K sound event dataset. The original files were converted from WAV to Opus to reduce the size and accelerate streaming.

• Sampling rate: 48 kHz
• Channels: 1
• Format: Opus
• Splits:
  • Dev: 80 hours, 40966 clips.
  • Eval: 28 hours, 10231 clips.
• License: FSD50K is released under CC-BY. However, each clip has its own licence. Clip licenses include CC0, CC-BY, CC-BY-NC and CC Sampling+. Clip licenses are specified in dev_clips_info_FSD50K.json and eval_clips_info_FSD50K.json.
