Question 1

Why are WAV files so large?

Accepted Answer

WAV stores raw, uncompressed PCM audio — every sample is kept at full precision. A stereo 16-bit 44100Hz WAV uses ~10MB per minute. This is by design: lossless quality for professional editing.

Question 2

When should I use WAV instead of MP3?

Accepted Answer

Use WAV for recording, editing, mastering, and any workflow where quality matters. Use MP3 for distribution, streaming, and web delivery where file size matters more than perfect quality.

Question 3

What is the difference between 16-bit and 24-bit WAV?

Accepted Answer

16-bit has 65,536 amplitude levels (CD quality). 24-bit has 16.7 million levels — much greater dynamic range. 24-bit is used in professional studios; 16-bit is standard for consumer audio.

Question 4

Can browsers play WAV files?

Accepted Answer

Yes. All modern browsers support WAV playback via HTML5 audio. However, WAV files are too large for web streaming — convert to MP3 or AAC for web delivery.
