Frequently Asked Questions
What is sample rate?
Sample rate is the number of audio samples captured per second, measured in Hz. Higher sample rates capture more detail but create larger files. Common rates: 44.1 kHz for music, 48 kHz for video.
What sample rate should I use?
44.1 kHz is CD quality and good for music. 48 kHz is standard for video and streaming platforms. Use our Quick Presets for automatic recommendations based on your use case.
Will resampling affect audio quality?
Downsampling removes high-frequency content above the Nyquist frequency. Upsampling doesn't add new detail but can improve compatibility. Our tool uses high-quality algorithms to minimize artifacts.
Are my files uploaded to a server?
No, all processing happens entirely in your browser. Your files never leave your device.
What output format is used?
Resampled audio is output as WAV format, preserving the highest possible quality.
