Technical Guide: Audio Quality and Formats

Understand the differences between bitrate, sample rate, and compression.

MP3 vs WAV: Which is better for you?

If you are looking for portability and low weight, MP3 is the universal standard. If you are a sound professional and need maximum fidelity without loss for further editing, choose WAV.

💡

DuneTools extracts audio directly from the data stream, minimizing quality loss.

What is Bitrate and why does it matter?

Bitrate determines how much audio information is processed per second. When extracting with our tool, we try to preserve the original bitrate of the video (typically between 128kbps and 320kbps) to ensure clear sound.

💡

Crystal clear audio: no metallic noise or aggressive server compression.
