Will reversing change the pitch or quality of the audio?

No. The audio samples are mapped in reverse chronological order, perfectly preserving sample rate, frequencies, and dynamic range.

What format is the downloaded reversed sound file?

The reversed file is saved as a studio-quality 16-bit PCM WAV file, compatible with any DAW, player, and video editing software.
