Description

WPT test https://github.com/web-platform-tests/wpt/blob/master/webcodecs/audio-encoder.https.any.js has channelNumberVariationTests and sampleRateVariationTests checking the input data matches the configuration of the encoder, but I see no mention of that in the spec.

Blink checks it, see https://source.chromium.org/chromium/chromium/src/+/main:third_party/blink/renderer/modules/webcodecs/audio_encoder.cc;l=509

Research direction

Read the WebCodecs AudioEncoder encode section and the WPT file webcodecs/audio-encoder.https.any.js, focusing on channelNumberVariationTests and sampleRateVariationTests. Compare those checks with Blink's audio_encoder.cc behavior, then clarify in the specification whether input channel count and sample rate must match the encoder configuration.
