Supported Azure Speech TTS output formats.

Remarks

A typed subset of the formats accepted by the X-Microsoft-OutputFormat header. Each format encodes a container, sample rate, and bitrate:

• audio-*-mp3 — MP3, best browser compatibility (default)
• riff-*-pcm — WAV (RIFF container, 16-bit PCM), uncompressed
• ogg-*-opus — Ogg Opus, good compression, open format
• webm-*-opus — WebM Opus, good for MediaSource playback
• raw-*-pcm — headerless 16-bit PCM for custom audio pipelines

See the Azure “Text to speech REST API” documentation for the full list.
