Will I Lose Quality?

Technically yes — MP3 is a lossy format — but at high bitrates like 192 or 320 kbps, most listeners won't notice any difference from the original WAV. For most purposes, it's a perfect compromise.

Audio Glossary

Bitrate:

The amount of data processed per second in an audio file, usually measured in kbps (kilobits per second). Higher bitrate means better quality and larger file size.

Sample Rate:

The number of audio samples captured per second, measured in Hz. Common values are 44.1 kHz (CD quality) and 48 kHz (video standard).

Channels:

Audio can be mono (1 channel) or stereo (2 channels). Stereo offers a more immersive sound experience.

CBR (Constant Bitrate):

Encoding mode where the bitrate stays the same throughout the entire file. Predictable file size, lower efficiency.

VBR (Variable Bitrate):

Encoding mode where the bitrate varies based on audio complexity. Higher efficiency and potentially better quality at the same average bitrate.

Lossy Compression:

A type of compression that removes some audio data to reduce file size. Formats like MP3, AAC, and OGG are lossy.

Lossless Compression:

Preserves 100% of the original audio data. Formats like FLAC and ALAC are lossless and ideal for archiving or editing.

WAV:

An uncompressed audio format offering high quality but large file size. Suitable for editing or archiving.

FLAC:

A lossless compressed format that maintains original quality while reducing file size. Great for storage and high-fidelity playback.

MP3:

The most widely supported audio format, using lossy compression to balance quality and size. Ideal for casual listening and sharing.
