To manage large WAV files produced by multi-channel recordings, what is required?

Compression is the correct approach for managing large WAV files generated from multi-channel recordings. WAV files, being uncompressed audio formats, can take up substantial amounts of storage, especially when there are multiple channels involved. By applying compression, these files can be reduced in size without significantly sacrificing audio quality. This makes storage, transfer, and handling of the audio data more efficient, especially when working with lengthy or high-fidelity recordings.

While segmentation can help in managing large files by breaking them into smaller, more manageable sections, it does not reduce the overall size of the data. Deletion of unnecessary channels might streamline the audio in terms of content but it does not address the size issue effectively if the essential channels still produce a large file. Conversion to a different format may also help, but it does not guarantee a reduction in size and could complicate compatibility with existing systems or workflows. Therefore, compression is the most effective method for addressing the concerns associated with large WAV files in a multi-channel context.
