Audio recording in Wav format (or uncompressed format).

I need to record audio in Wav format (or another uncompressed format) without using external apps which can interface with Tasker.

I know we're talking about smartphones and not professional equipment, but for the same device, by recording Wav files with external app plugin, I get a much higher quality sound than Tasker. On the other hand, Tasker offers better control over recordings, file management, and does not require tricks with time delays to make sure the recording is saved.
