Sample rate is how many snapshots per second a digital recording takes, and different worlds demand different numbers: music distribution standardized on 44.1 kHz (the CD rate), everything video lives at 48 kHz, and archival or studio interchange often wants 88.2 or 96 kHz. StudioWavePro’s converter shows your file’s current rate and offers six targets — 22.05, 32, 44.1, 48, 88.2 and 96 kHz — labeled with what they’re for.

The conversion runs through high-quality resampling, recalculating the waveform at the new rate; duration and pitch stay exactly the same, only the internal sample grid changes. The most common real-world need is the 44.1 ↔ 48 hop — handing music to a video editor or pulling video audio into a music project — where a mismatched rate either gets refused or plays at chipmunk/slow-motion speed in less careful software.

When to use

Convert a 44.1 kHz music track to 48 kHz for a video project or DaVinci/Premiere spec.
Bring 48 kHz video audio to 44.1 kHz for music distribution or CD.
Downsample to 22.05 or 32 kHz for telephony, embedded devices, or small voice files.
Conform a batch of mixed-rate clips to one rate before merging them elsewhere.
Deliver 88.2/96 kHz versions to a studio or archive that requests them.

How to use

Click "Open Sample Rate Converter" below to launch the editor.
Drop in any audio file — MP3, WAV, OGG, M4A and FLAC are all supported; the panel shows its current rate.
Pick the target: 22.05k, 32k, 44.1k (CD), 48k (video), 88.2k or 96k (studio).
Click Apply — duration and pitch are preserved exactly; only the sample grid changes.
Download as WAV or MP3.

Tips

Rule of thumb: 44.1 kHz for music releases, 48 kHz for anything destined for video. When in doubt for modern platforms, 48 kHz is the safer default.
Upsampling (44.1 → 96) never adds quality — it just re-grids the same information into a bigger file. Do it to meet a spec, not to "improve" audio.
Downsampling permanently discards content above the new Nyquist limit (half the target rate). 22.05 kHz keeps audio up to ~11 kHz — fine for speech, dull for music.
Resample as the last step when possible: process at the original rate, convert once at the end, and you avoid stacking conversions.
Joining clips with different rates? The Audio Merger and Crossfade Joiner conform rates automatically — you only need this tool when the final rate itself must be specific.

Frequently asked questions

What sample rate should I use?: Music for streaming/CD: 44.1 kHz. Anything attached to video: 48 kHz. Speech where size matters (IVR, embedded): 22.05 or 32 kHz. Studio interchange/archival: 88.2 or 96 kHz when requested. Matching the destination spec matters more than the absolute number.
Does converting the sample rate change pitch or speed?: No — proper resampling recalculates the waveform on a new grid while preserving its shape in time, so duration and pitch are identical. (The chipmunk effect happens only when software plays samples at the wrong rate without converting, which is exactly the problem this tool prevents.)
Will I lose quality converting 48 kHz to 44.1 kHz?: Technically the content between 22.05 and 24 kHz is discarded — frequencies no human hears. For any normal material the conversion is audibly transparent. Avoid repeated back-and-forth conversions, though; do it once at the end of your workflow.
Does converting to 96 kHz make my audio sound better?: No — upsampling cannot create information the recording never captured. It exists for compatibility: meeting a delivery spec, matching a session rate, or feeding gear that requires it. The file just gets bigger.
Why does my audio play too fast or too slow in some software?: That’s a sample-rate mismatch: the file says one rate, the player or project assumes another, and every sample plays early or late — shifting both speed and pitch. Converting the file to the project’s rate with this tool fixes it at the source.
What sample rate do my files have right now?: Drop the file into the tool — the panel shows the current rate immediately, next to the target options. (The Apply button stays disabled if you pick the rate the file already has.)
