How to Change the Sample Rate of an Audio File
Resample audio files to different sample rates for compatibility with specific devices, platforms, or professional audio standards.. This step-by-step guide walks you through the process using LevnTools Audio Resampler, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.
Upload your audio file
Upload the audio file you need to resample. The tool detects and displays the current sample rate, bit depth, channel count, and file format. Common source rates are 44.1kHz for CDs and 48kHz for video.
Select the target sample rate
Choose the desired output sample rate. Use 44.1kHz for CD and music distribution, 48kHz for video and broadcast, 96kHz for high-resolution mastering, or 22.05kHz for telephony and voice applications.
Choose the resampling algorithm
Select the conversion quality. High-quality sinc interpolation produces the best results but takes longer. Linear interpolation is faster for non-critical applications. Always use high quality for music.
Resample and download
Click Resample to process the file. The tool applies anti-aliasing filtering to prevent artifacts when downsampling. Download the resampled file in your preferred format.
Pro Tips
- When preparing audio for video, always resample to 48kHz. All major video formats including MP4 and MOV use 48kHz as the standard audio sample rate.
- Upsampling from 44.1kHz to 96kHz does not add audio quality or detail that was not in the original recording. Only upsample when required by a specific workflow or device.
- Downsampling from high rates like 96kHz to 44.1kHz requires proper anti-aliasing. Always use the high-quality algorithm to prevent aliasing artifacts that sound like metallic ringing.
Common Issues & Fixes
Issue: The resampled audio has a high-pitched ringing or metallic quality.
Fix: This is aliasing from insufficient anti-aliasing filtering during downsampling. Reprocess the file using the high-quality sinc interpolation algorithm.
Issue: The file size increased dramatically after resampling.
Fix: Upsampling to a higher rate like 96kHz or 192kHz proportionally increases file size. If you do not need high-resolution audio, resample to 44.1kHz or 48kHz instead.
Issue: My DAW or video editor will not import the resampled file.
Fix: Check the format compatibility. Some software has strict requirements for both sample rate and bit depth. Try exporting as 48kHz 16-bit WAV which is universally supported.
