What sample rate does Suno actually export at in 2026?

There is no published guarantee. Current WAV exports are reported at either 44.1 kHz or 48 kHz depending on the Suno version and account, so the only reliable answer is what `ffprobe` shows for your file. Do not trust spec tables, including older versions of this article that said "always 44.1."

Why can't I find a 48 kHz export option in Suno?

There is no in-app sample-rate dropdown. Suno picks the rate; you convert downstream. If your file is already 48 kHz for a video project, you are set; if it is 44.1, convert with Step 3.

Does converting 44.1 kHz to 48 kHz lose quality?

A tiny amount, but with a good resampler (SoX, or ffmpeg's `soxr` at `precision=28`) it is inaudible. Cheap linear-interpolation resamplers cause audible high-frequency roll-off, which is why you convert once, offline, rather than letting each tool do it.

My "Suno WAV" reports 32 kHz or looks like an MP3. Why?

You likely downloaded on mobile (which often defaults to MP3) or used a third-party downloader that re-encoded the file. Re-download the WAV from the web app on a Pro/Premier account and re-check with `ffprobe`.

Should I keep the project at 44.1 or 48 kHz?

Match your final delivery target, not Suno. Streaming/CD: 44.1. Video/broadcast/podcast: 48. If you do both, keep two masters.

Troubleshooting

Suno WAV Export Sample Rate Mismatch: Fix 44.1 vs 48 kHz

Your DAW or video editor flags a sample rate mismatch on a Suno WAV. Confirm the real rate with ffprobe, convert losslessly with SoX/ffmpeg, and stop silent resampling.

You export a Suno track as WAV, drag it into your DAW or video editor, and get a warning: Sample rate mismatch — this file is 44.1 kHz, your project is 48 kHz. Convert? Or worse, no warning at all: the file gets silently resampled on import, the top end on cymbals and sibilance comes out washed out, and you don’t notice until the mix is rendered.

Fastest fix: don’t guess Suno’s rate, measure it. Run ffprobe -show_entries stream=sample_rate yourfile.wav. If it already matches your project (often 44100), nothing is wrong. If it differs, convert once, offline, with a high-quality resampler (ffmpeg ... -af "aresample=resampler=soxr:precision=28" -ar 48000) and import only that converted file. Never let your DAW and your video editor each resample the same file.

One thing changed and it matters as of June 2026: Suno does not publish a guaranteed export sample rate, and it is no longer safe to assume “always 44.1 kHz.” WAV export (Pro/Premier tiers, on the web app) from current Suno builds (around v5.5, exported via Suno Studio) is reported at either 44.1 kHz or 48 kHz depending on the version and account. There is still no in-app dropdown to choose the rate. So the first step is always to inspect the actual file, not trust a spec sheet. Below: why this happens, how to convert without aliasing or pitch shift, and which workflows hide silent resampling bugs.

Which bucket are you in?

Match your symptom to a cause before you touch any converter. Most “wrong sample rate” reports are actually case 1 or 3.

Symptom	Likely cause	Fix section
Explicit “sample rate mismatch” dialog on import	File rate differs from project rate	Cases 1-2, Steps 1-3
No warning, but top end sounds dull after import	DAW/editor silently resampled cheaply	Cases 3-4, Step 7
Audio plays too fast/slow and pitched on one device only	Playback speed mismatch, no resampling	Case 5
Tracks from the same Suno session report different rates	Mixed export paths or a re-encoded download	Cases 6-7, Step 1

Common causes

Ordered by hit rate.

1. Suno’s file rate differs from your video project’s 48 kHz

Video projects (YouTube, Final Cut, Premiere, DaVinci, broadcast) standardize on 48 kHz. Music projects (Spotify, Apple Music, CD) use 44.1 kHz. Suno targets music, so its WAV is commonly 44.1 kHz, though some current builds export 48 kHz. Either way, if the file rate and the project rate disagree, you get the warning.

How to spot it: Right-click the WAV in your OS file inspector and look at “Sample rate” or “Format”, or run ffprobe (Step 1). The exact number is what matters; do not assume it is 44100. Your project’s rate is set in DAW/editor preferences.

2. Account or version exports at an unexpected rate

Export specs are not officially published and have shifted across Suno versions. WAV is a Pro/Premier feature on the web app; on mobile the download button often defaults to MP3, so a “WAV” grabbed on a phone may actually be a 44.1 kHz MP3 rebadged by a third-party tool. Older or free-tier accounts have been reported exporting at lower rates (for example 32 kHz). The point: inspect every file, do not trust a tier-based assumption.

How to spot it: Run ffprobe yourfile.wav or check Audacity File Info. If it reports something other than 44100 or 48000, that account/version path is giving you a non-standard rate.

3. Your DAW silently resampled on import

Reaper, Logic, Ableton, and Pro Tools all auto-resample imported files to match project rate by default. The conversion may use a fast / low-quality resampler. Audible result: slight top-end roll-off, transient softening.

How to spot it: Look at the project’s audio file folder. Imported file is now bigger (or different size) than the original WAV. The DAW wrote a converted cache file.

4. Video editor resampled with cheap algorithm

Premiere, Final Cut, DaVinci all do their own resampling. Default quality varies. Premiere historically used a linear interpolation resampler by default (poor quality).

How to spot it: Compare exported video audio bus to original Suno WAV in a spectrum analyzer (free Voxengo SPAN). Look for high-frequency roll-off above 18 kHz that the original didn’t have.

5. Pitch shifted by playback rate mismatch (no resampling)

Some old players and embedded systems play a 44.1 kHz file at 48 kHz speed — about 9% faster and pitched up roughly 1.6 semitones. Modern OSes don’t do this anymore, but legacy hardware (DSP-based video cards, some IoT speakers) might.

How to spot it: File plays back faster / pitched up only on specific hardware. Plays fine in VLC / QuickTime.

6. Suno MP3 vs WAV report different rates

Suno MP3 export can be 44.1 kHz; WAV export same. But Pro stem exports may differ. Check each file individually rather than assuming.

How to spot it: ffprobe each file from a Suno session. Inconsistencies between tracks from the same session mean you cannot assume one rate.

7. You used a third-party Suno downloader that re-encoded

Browser-extension or shell-script downloaders sometimes re-encode the audio with arbitrary settings. The “Suno WAV” you have may not be Suno’s native file.

How to spot it: Compare file size of the official Suno download button output vs your extension download. Different sizes = re-encoded.

Shortest path to fix

Step 1: Confirm Suno’s actual export rate

ffprobe -v error -show_entries stream=sample_rate,channels,bits_per_sample yourfile.wav

Output looks like:

[STREAM]
sample_rate=44100
channels=2
bits_per_sample=16
[/STREAM]

A typical Suno music WAV reports sample_rate=44100, channels=2, bits_per_sample=16. If you instead see 48000, that is also a valid current Suno export, not an error. Write the number down; every later step depends on it.

Step 2: Decide target rate

Music distribution (Spotify, Apple Music, CD): 44.1 kHz. If your Suno file is already 44.1, no conversion needed.
Video (YouTube, broadcast, podcast): 48 kHz.
Film / cinema: 48 kHz at 24-bit minimum.
Game audio: depends on engine (Unity / Unreal often 48 kHz).

The rule: convert only when the file rate from Step 1 differs from the target. If they already match, skip to verification.

Step 3: Convert with a quality resampler (offline)

Use ffmpeg’s SoX resampler (soxr) at very-high-quality precision. The -af aresample filter does the resampling; -ar 48000 sets the output rate:

ffmpeg -i input.wav -af "aresample=resampler=soxr:precision=28" -ar 48000 output_48k.wav

precision=28 is SoX’s “Very High Quality” setting (the default is 20, “High Quality”). To go the other direction, set -ar 44100.

Or use SoX directly:

sox input.wav -r 48000 output_48k.wav rate -v -L

In the SoX rate effect, -v selects very-high-quality and -L selects a linear-phase filter.

Step 4: Verify the conversion didn’t shift pitch

First reconfirm the rate actually changed: run ffprobe (Step 1) on the output and check it reports your target. Then open input and output in Audacity and use Analyze → Plot Spectrum on the same passage of both. The two clips have the same duration and the spectral peaks land at identical frequencies. If the output is shorter/longer and the peaks are shifted by a fixed ratio (for example 1.088x = 48/44.1), you got speed-shifted instead of resampled; redo with the explicit -ar flag and avoid any “change speed/tempo” tool.

Step 5: Set DAW / video project to match Suno before importing

If you have not started the project yet, set it to 44.1 kHz and avoid the issue entirely. Music projects gain nothing from 48 kHz unless your delivery target is video.

Step 6: For video work, convert ONCE upstream

Don’t let three different tools each resample the same file. Convert Suno WAV → 48 kHz once with SoX / ffmpeg, then import only the converted file into Premiere / Final Cut.

Step 7: Disable cheap resampling in your DAW

Reaper: Preferences → Audio → Buffering → Resample quality = Better. For final render: Best.
Ableton: Preferences → Record / Warp / Launch → High-Quality Sample Rate Conversion = On.
Logic: Preferences → Audio → General → Sample Rate Conversion Quality = Best.
Pro Tools: the import dialog has a “Conversion Quality” dropdown; set it to TweakHead.

How to confirm it’s fixed

You are done when all three are true:

ffprobe on the file you actually import reports your target rate (no surprises).
Your DAW/editor imports it with no sample-rate-mismatch dialog and writes no converted cache copy.
A spectrum check (Step 4) shows no new high-frequency roll-off versus the original Suno WAV.

For video, run ffprobe on the final rendered export too and confirm the audio stream matches your delivery target. That one check catches the most common silent failure: a clean intermediate file that an editor re-resampled at render time anyway.

When this is not on you

Suno gives you one export rate with no per-file dropdown to change it. If your downstream pipeline needs a different rate, conversion is mandatory and not a bug. The rate is also not officially documented and has changed across versions, which is exactly why Step 1 (inspect, don’t assume) leads.

The perceptual difference between 44.1 and 48 kHz on modern playback is minor; most listeners cannot hear it. The real risk is silent, repeated, low-quality resampling stacking up audible artifacts.

Easy to misdiagnose as

Suno mastering clipping loud — this is about peak level, not sample rate.
Suno pitch shift on vocal — that is per-voice pitch, not a global playback rate issue.
MP3 quality low — bit rate / codec quality, not sample rate.
DAW playback is choppy — buffer / driver issue, not export rate.

Prevention

Match project sample rate to your delivery target before importing any Suno audio.
Keep one canonical “converted” copy of each Suno track for video pipelines. Don’t re-convert at every step.
Use SoX or ffmpeg with soxr / sinc resamplers, not the DAW’s default fast resampler, for the master conversion.
Audit a sample of finished video exports with ffprobe to confirm final audio sample rate matches your target.
If you publish a Suno track to streaming AND embed it in a YouTube video, keep two masters — 44.1 for streaming, 48 for video.
