Improve match results (iOS/ Android)

The resulted matches from a custom catalog on both iOS/ Android are a bit delayed (1-3+ seconds)

How to test? (iOS)

1. Prepare AVAudioPlayer with recorded audio.
2. Load custom catalog & listen to recorded audio from an external source.
3. When a match is found, play recorded audio from the AVAudioPlayer at: predictedCurrentMatchOffset

Result: 1-3+ seconds delayed matches

Question

How to improve or filter the resulting matches to be close if not exact to the external audio source?

Experimental

Filtering results by frequencySkew close to 0, does not minimize delayed matches.

[{
    "sh_audioStartDate" = "2021-11-24 12:34:42 +0000";
    "sh_frequencySkew" = "2.222024e-05";
    "sh_matchOffset" = "388.3738065670163";
    "sh_score" = "4302.546";
    "sh_speedSkew" = "0.0009712927";
    "sh_title" = ItemTitle;
}]

Printing the matchedMediaItems, there is a “sh_score”, maybe we can experiment with? But it’s not a public property

Best regards.
