Sample Rate Converter Online
Resample any audio file to 44.1 kHz, 48 kHz, 16 kHz, and more right in your browser. Pitch and length stay exactly the same — no sign-up, and your file is never uploaded.
How to Convert Audio Sample Rate
No account, no upload — three steps on your own device.
Drop Your Audio
MP3, WAV, M4A, FLAC, OGG, or AAC up to 200 MB. It decodes in the browser and shows your file's current sample rate.
Pick a Target Rate
Tap 8, 16, 22.05, 44.1, or 48 kHz. The preset your file is already at is disabled — nothing to convert there.
Convert & Download
Hit convert, preview the result, then save it as an MP3 at the bitrate you like. Pitch and length stay identical.
Why Notevibes Sample Rate Converter
Same pitch, same length — only the rate changes.
One-Tap Target Rates
Pick 8, 16, 22.05, 44.1, or 48 kHz with one tap. The tool reads your file's current rate on load and disables the preset you're already at.
Pitch & Length Preserved
True resampling — the audio plays back at the same speed and the same pitch. Only the sample rate changes, nothing else.
Never Uploaded
Resampling runs entirely in your browser. Your file never leaves your device — there is nothing to delete because nothing was sent.
The Rates That Matter
44.1 kHz for music and streaming, 48 kHz for video and broadcast, 16 kHz for speech and transcription pipelines, 8 kHz for telephony.
Preview, Then Download
Listen to the resampled result before saving it as an MP3 at the bitrate you choose — anywhere from 64 to 320 kbps.
Free, Anywhere
No watermark, no sign-up, no daily limits. Works on phones, tablets, and laptops in any modern browser.
Nothing to Upload, Nothing to Leak
The resampling happens on your own device. Your file never touches a server — which is a stronger promise than any “we delete it later”.

When to Convert Sample Rate
One tool for every “wrong sample rate” moment.
Match Video at 48 kHz

Telephony at 8 kHz
Downsample for IVR systems, phone prompts, and voice-over-IP
Prep for a DAW
Convert imports to your project's session rate before mixing
Fix Import Errors
Resolve “wrong sample rate” and “unsupported rate” messages on import
Speech Models at 16 kHz
Resample for transcription, ASR, and voice ML pipelines
Standardize a Batch
Bring a mixed folder of files onto one consistent sample rate
When the Rate Is Wrong, Nothing Imports
A video editor that insists on 48 kHz, a phone system that only takes 8 kHz, a transcription pipeline built for 16 kHz — and your file is 44.1. The usual fixes are uploading to a converter site and waiting in a queue, or installing a DAW for a ten-second job. This tool skips both: drop the file, tap a rate, and your browser resamples it on the spot.
Same pitch, same length, new rate
This is true resampling, not a sped-up trick — the samples are recalculated for the new rate, so the audio sounds exactly the same to the ear and runs exactly as long. Going down to 16 or 8 kHz deliberately drops the highest frequencies, which is precisely what speech models and telephony systems expect. Going up won’t invent detail, but it makes the file a first-class citizen in a 48 kHz project.
Private by physics, not by promise
Converter sites promise to delete your upload eventually; this one never receives it. The file stays on your device from drop to download, which makes it safe for client work, unreleased mixes, and recordings you’d rather not park on a stranger’s server. It runs on the same resampling code the full Notevibes editor uses for its renders.
Honest controls, zero gatekeeping
The tool shows your source rate the moment the file decodes and disables the preset you’re already at — it won’t re-encode your audio just to hand you back the same rate. You preview the result before downloading, and because your device does the work there’s nothing to meter: no watermark, no daily cap, no sign-up, files up to 200 MB.
If the rate isn’t the only problem
Need a different format or WAV output? The audio converter handles format, bit depth, and channels the same no-upload way. To shrink an MP3 without touching the rate, use the audio bitrate changer, and if the file is too quiet, the audio normalizer brings it up to level.
Need to Do More Than Resample?
The full Notevibes editor trims, mixes, cleans up, and applies AI tools to your audio — then exports to MP3 or WAV.

Sample Rate Converter FAQ
What is a sample rate?
The sample rate is how many audio samples are stored per second, measured in hertz (Hz). 44,100 Hz (44.1 kHz) is the CD and music standard; 48,000 Hz (48 kHz) is the video and broadcast standard. A higher rate captures higher frequencies.
Does converting the sample rate change the pitch?
No. This is a true resampler — it recalculates the samples for the new rate, so the audio keeps the exact same pitch and the exact same duration. Only the sample rate changes.
44.1 kHz vs 48 kHz — which should I use?
Use 44.1 kHz for music, CD, and streaming audio. Use 48 kHz for video, film, and broadcast — it's the standard most video editors and platforms expect. Matching the surrounding project avoids resampling artifacts down the line.
Why is one rate button disabled?
The preset that matches your file's current sample rate is disabled — there's nothing to convert. The tool shows your source rate next to the file name, so you can see exactly what you're converting from.
Will downsampling lose quality?
Lowering the sample rate (e.g. 48 kHz → 8 kHz) discards the highest frequencies, which is expected and exactly what telephony or speech models want. Raising the rate (e.g. 44.1 → 48 kHz) won't add detail that wasn't there, but makes the file compatible with higher-rate workflows.
Is my audio file uploaded to a server?
No. The sample rate converter runs entirely in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded, stored, or analyzed.
What audio formats are supported?
MP3, WAV, M4A, FLAC, OGG, and AAC — anything your browser can decode, up to 200 MB. After converting you can preview the result and download it as an MP3 at any bitrate from 64 to 320 kbps.
