AEC Challenge 48 kHz Community Mirror

This dataset is a community mirror of the 48 kHz synthetic_fullband data from the 2022 AEC Challenge. The original upstream download is no longer available.

The recovered archive contains three synchronized audio tracks:

  • target: near-end target speech
  • mic: microphone mixture
  • farend: far-end reference audio

This is not an official Microsoft repository. The mirror preserves the recovered archive as-is and does not add generated training samples.

Scope

This recovered subset does not contain the separate echo and nearend component tracks available in some AEC Challenge distributions. It is suitable for workflows that use synchronized target, mic, and farend tracks, but it cannot support component-level echo attribution without additional processing.
