Depends. The Arbitron system works through the HD Radio codec, which is a wavelet codec. It is basically hybrid mp3 type coupled with high frequency reconstruction on the receiver side.

Interestingly, that literally means fake signals on the receiving end above 8 to 10Khz! Was as low, and may still be as low as 5khz when used for AM. I have not kept up.

I could tell early on. It has improved a lot since then.

The Arbitron system appears robust. Noise, low signal quality, etc... do not generally impact it much. The effective bitrate needed is very low.

Given a larger sample of audio, it is likely to work.
