Specification https://w3c.github.io/webcodecs/opus_codec_registration.html#dom-opusencoderconfig-signal Summary `OpusEncoderConfig.signal` and `OpusEncoderConfig.application` were recently added to the WebCodecs spec [1]. Both parameters are mapped directly to implementation specific encoder knobs. These allow web authors to provide hints as to what type of data is being encoded, and in which context the data is being used. `signal` can be one of {"auto", "music", "voice"}. It configures the encoder for the best performance in encoding the specified type of data. `application` can be one of {"voip", "audio", "lowdelay"}. It configures the encoder to favor speech intelligibility, faithful reproduction of the original input, or minimal latency.

For an almost identical feature, Mozilla said the "request for standards position" was not warranted, as they were active spec participants: https://github.com/mozilla/standards-positions/issues/837#issuecomment-1614666364 *WebKit*: No signal. Review from WebKit was requested on the spec change. *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes Existing WPTs will be modified to cover this feature: https://wpt.fyi/results/webcodecs/audio-encoder-config.https.any.html Flag name on chrome://flagsNone Finch feature nameNone Non-finch justification Simple parameter changes.

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
