Frequently Asked Questions

What are zero-crossing recordings?

Rather than representing the full waveform, or shape, of sound information in the way that most conventional, full-spectrum audio recordings in any application do, zero-crossing is a compact way of representing only the most prominent frequency in a recording by noting the points in time at which a sound wave has crossed a reference amplitude a certain number of times.

For a more detailed explanation of the trade-offs involved with zero-crossing recordings, please see this presentation.
