Fix Dynamic Sample Rate Detection for Audio Compatibility

[mmtmn]

On Firefox, we get the issue:

Here is the explanation to this fix:

Connecting AudioNodes from AudioContexts with different sample-rate is currently not supported.

• getSystemSampleRate(): This helper function will dynamically detect the system's default sample rate by creating a new AudioContext instance and querying its sampleRate property. This is important because different browsers and devices may have different default sample rates, and this will prevent sample rate mismatch issues.
• Changes in WavStreamPlayer and WavRecorder: By using new AudioContext().sampleRate as the fallback, the application adapts to the system's default sample rate if none is explicitly provided. This is critical for maintaining compatibility across different browsers, particularly Firefox, which enforces stricter rules on sample rates.

These are the changes needed to ensure your application works seamlessly with the system's default audio configuration without causing issues, particularly in Firefox.

For the Realtime API we need a 24,000 Hz sample rate. Do you think there's another solution to this problem? This is Firefox only, correct?

@khorwood-openai From my brief testing this happens on Firefox and not Safari.

Ah, I see. I think there might be a way around this but I'm not sure. I'll report back in a few minutes.

Working on a resample audio to 24,000 Hz solution to this pull request, should be updating this shortly

[mmtmn]

Ok, I think resampling should be working, just improving a bit on the resampling efficiency. Once I get the resampling efficient I'll update the PR.

@khorwood-openai I've added resampling to this pull request, it should be good to review now.

@khorwood-openai any updates on this? This fixes issue #5
