Decode encoded audio into waveform rows.

Equivalent to audio_decode(). See that function for full parameter details.

Parameters

on_error – "raise" to propagate corrupt audio failures, or "null" to return null for rows that cannot be decoded.
max_decoded_bytes – Maximum decoded PCM payload allowed per row.
concurrency – Optional execution concurrency for this operation. None uses the framework default.

A DataFrame expression that produces decoded audio waveform ROW values.
