Understanding sample rates, bit rates, and quality settings will help you export audio that's perfectly optimized for your specific use case while managing file sizes effectively.
Sample rate determines how many times per second the audio waveform is measured, measured in Hertz (Hz) or kilohertz (kHz). Higher sample rates capture more detail but create larger files.
Bit depth determines the dynamic range and noise floor of your audio. Higher bit depth provides more headroom and lower noise but increases file size.
Bitrate determines how much data is used to represent each second of audio in compressed formats like MP3 and AAC. Higher bitrates mean better quality but larger files.
Not necessarily. Export quality should match your intended use. For professional mastering, use the highest quality (24-bit/96kHz WAV). For web streaming, 320kbps MP3 is more practical and virtually indistinguishable for most listeners.
44.1kHz is the CD standard and optimal for music. 48kHz is the video/film standard and should be used when your audio will accompany video. The quality difference is negligible for most applications.
For compressed formats (MP3, AAC), yes, but with diminishing returns above 256-320kbps. The improvement from 256kbps to 320kbps is much smaller than from 128kbps to 192kbps.
No. Exporting low-quality audio to a high-quality format doesn't restore lost information. Always maintain the highest quality throughout your production workflow.
