Split-band compression circuit, audio signal processing method and audio signal processing system

A split-band compression circuit includes first stage filters, split-band limiters, and second stage filters. The first stage filters are configured to receive and filter an input signal to output first split-band signals. The split-band limiters are coupled to the first stage filters respectively,...

Zusammenfassung:A split-band compression circuit includes first stage filters, split-band limiters, and second stage filters. The first stage filters are configured to receive and filter an input signal to output first split-band signals. The split-band limiters are coupled to the first stage filters respectively, and configured to perform compression on the first split-band signals to output second split-band signals. The second stage filters are coupled to the split-band limiters respectively, and configured to filter corresponding second split-band signals to output output signals. The first stage filter and the second stage filter corresponding to the same split-band limiter have different cut-off frequencies respectively.
