Abstract
A method and an apparatus for determining an echo, and a storage medium. The implementation solution includes: obtaining an echo estimation result by performing echo estimation on an original audio signal; obtaining an optimization processing result by performing optimization processing on the echo estimation result, the optimization processing includes at least one of amplitude dimension optimization processing, phase dimension optimization processing, or time domain dimension optimization processing; and determining an echo of the original audio signal using the optimization processing result.
