Frequently Asked Questions
What is WAV format?
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM. It stores audio in its raw, unprocessed form without any quality loss.
What bit depth should I use?
16-bit is CD quality and suitable for most uses. 24-bit offers greater dynamic range and is preferred for professional audio production. 32-bit provides the maximum quality for advanced production work.
What sample rate should I choose?
48 kHz is standard for video and professional audio (recommended for AC3 sources). 44.1 kHz is CD quality. 96 kHz is for high-resolution audio.
Why are WAV files so large?
WAV files are uncompressed, storing audio in its raw form. A 3-minute stereo 16-bit/44.1kHz WAV is about 30MB. This is the tradeoff for perfect quality with no compression artifacts.
WAV vs FLAC - which is better?
WAV and FLAC have identical audio quality. FLAC files are 40-60% smaller due to lossless compression. Use WAV for maximum compatibility, FLAC for efficient storage.
