Understanding WAV vs MP3
About WAV
WAV (Waveform Audio File Format) is an uncompressed audio container developed by Microsoft and IBM. It stores raw pulse-code modulation (PCM) audio samples, making it ideal for professional studio recording but too large for consumer sharing.
About MP3
MP3 utilizes psychoacoustic compression to discard audio frequencies that human hearing cannot detect, achieving dramatic size reductions without noticeable loss of perceived musicality.
When to Use WAV vs MP3
Keep WAV for mastering, multitrack mixing, and archiving. Convert to MP3 for distribution, podcast feeds, streaming previews, and everyday playback.
Quality & Fidelity Retention Notes
Switchr encodes at transparent bitrates so subtle vocal nuances and stereo imaging remain preserved.
