Single-file processing is described as reasonably fast, but multi-file uploads increase processing time noticeably.

Processing was reasonably fast for one file, but uploading three files together increased processing time noticeably.

The processed audio significantly altered the original speaker's tone and voice characteristics, so the output sounded less natural and did not closely match the source.
