The SARTRE tag suggests a smaller release group. No mention of bitrate or specific audio channels, so assume moderate settings.

Here’s a review of that specific release:

AAC audio. This is a lossy codec—acceptable for casual viewing, but purists would prefer AC3 or DTS from the original BluRay. Since the original mono track doesn’t need high bitrate, AAC is fine for dialogue clarity. No mention of multiple tracks; likely just the original English mono.
