- Download the adjusted audio instantly
Change Audio Bitrate and Sample Rate Online for Free
Control the quality and file size of your audio by setting its bitrate and sample rate. Lower the bitrate to shrink a file for sharing, or pick a higher one for better quality. You can also change the sample rate to meet a technical requirement. The result downloads in the same format you uploaded. No sign-up and no watermarks.
How to Change Bitrate
- Click the upload area above or drag and drop your audio file (up to 10 MB).
- Pick a bitrate (64–320 kbps) and a sample rate (8 kHz–192 kHz). The panel shows your file's current values to compare against.
- Apply and download your adjusted audio.
Understanding Bitrate and Sample Rate
- Bitrate (kbps) – how much data is used per second of audio. Higher bitrate = better quality but a bigger file. Common values: 128, 192, 256, 320 kbps.
- Sample Rate (Hz) – how many audio samples are taken per second. Common values: 22050, 44100 (CD), 48000 Hz (video).
Common Bitrate Settings
- 64 kbps – low quality, very small files; fine for speech only
- 128 kbps – standard quality for general listening
- 192 kbps – good quality, balanced size and fidelity
- 256 kbps – high quality, hard to tell from the original
- 320 kbps – maximum MP3 quality
Frequently Asked Questions
For music, 192–320 kbps gives excellent quality. For speech and podcasts, 96–128 kbps is plenty. For voice memos or phone audio, 64 kbps works fine.
No. Raising the bitrate of an already-compressed file can't restore detail that was lost — it only makes the file bigger. For the best result, start from the highest-quality source you have.
Not really. WAV is uncompressed and FLAC is lossless, so they don't use a target bitrate — for those files only the sample rate change applies. Bitrate matters for compressed formats like MP3, OGG, M4A and AAC.
44100 Hz (CD quality) is the standard for music, 48000 Hz is standard for video audio, and 22050 Hz is enough for speech-only content.
