❓ Frequently asked questions 4 answers

MP3 is a compressed format — converting to WAV gives you an uncompressed, lossless copy suitable for editing, mastering, or professional audio work. WAV is also compatible with audio editing software, studios, and archiving systems.

Yes, typically 10-20x larger. An MP3 optimized for streaming (128-320 kbps) expands to full CD-quality WAV (1,411 kbps). This is expected and necessary for lossless quality.

No. The converter cannot recover data discarded during MP3 compression. It creates a lossless WAV container for the MP3 stream, but the audio quality is limited to what the MP3 contained. For best results, start with a high-bitrate MP3 (320 kbps) or a lossless source.

Output is standard CD-quality WAV: 44.1 kHz sample rate, 16-bit depth, stereo channels. This is compatible with all audio editing software and professional workflows.
