AudioSpace calculates the amount of storage required by an audio recording of a given duration, for different sampling rates, resolutions, and numbers of channels. The calculation may be made for uncompressed audio data or for several types of compression. A variety of units may be selected for reporting the result. The calculation may also be inverted to determine the maximum duration of audio that will fit into the available storage.
