Is that recording good enough to send, post or broadcast? This audio quality test listens to a finished file and grades it the way an engineer would on a first pass. It scores clarity, background noise, distortion, dynamic range and frequency balance from 0 to 100, gives an overall production rating, and lists each problem it hears with how serious it is: a faint hum that most people will miss, or clipping that will make listeners wince. Every issue comes with a practical recommendation, whether that means re-recording, moving the microphone or cleaning it up in an editor. It works on voice recordings, podcast episodes, video soundtracks and music alike. Note that it checks a recorded file rather than running a live microphone meter, so record a short sample first and upload that.
Example result
Input
A 3-minute podcast intro recorded on a USB microphone in a home office, exported as MP3.
Output
Overall: usable for a podcast, but two issues hold it back. Issue 1 (moderate): a steady low hum around mains frequency sits under the voice throughout. Likely a ground loop or a laptop charger near the interface. Try unplugging the charger and re-recording 10 seconds to confirm. Issue 2 (minor to moderate): plosives on "p" and "b" words at 0:42 and 1:15 briefly clip. A pop filter or angling the mic slightly off-axis will fix it. Frequency balance: slight boominess below the voice from sitting close to the mic; a gentle low cut would clean it up. Dynamic range: natural, not over-compressed. Clarity: speech is easy to follow; consonants are crisp.

How it works
How Audio Quality Checker works
- 01
Upload a representative clip
Sign in, open the checker and add the file, or record a sample in your browser. Pick the AI model you want to run the check.
- 02
Noise and distortion sweep
The AI listens for hiss, electrical hum, room tone and other background sound, then for clipping, over-compression and digital artifacts such as warbling from heavy noise reduction or low bitrate encoding.
- 03
Dynamics and tonal balance
It judges whether loud and quiet moments have room to breathe or are squashed flat, and whether the lows, mids and highs are balanced or the sound is boomy, muddy, thin or harsh.
- 04
Ranked issues and fixes
You get a score for each metric, an overall production rating, and a list of problems ordered by severity with a recommendation for each.
Use cases
Who it is for
Podcasters before publishing
Run a test recording in your usual setup and catch hum, echo or clipping before you commit a full episode to it.
Remote workers and job seekers
Record a short sample on the headset or laptop you plan to use for an important call or a recorded interview and see whether your sound quality helps or hurts you.
Video creators
Check the dialogue track of a video edit for noise and harshness, which viewers forgive far less than slightly soft picture.
Anyone comparing microphones
Record the same sentence on two mics or two positions and compare the scores side by side to decide which setup to keep.
Tips
Get better results
- Upload the original file if you can. A clip that has been compressed by a messaging app will score lower than the recording itself.
- Include a couple of seconds of silence before you speak so the AI can hear your room's noise floor on its own.
- Test the loudest part of the recording, such as laughter or a chorus, since that is where clipping usually shows up.
- Change one thing at a time between tests (mic distance, room, gain) so you know which change moved the score.
- Treat severity as your to-do order: fix problems rated severe before chasing small frequency tweaks.
Limitations
What it can't tell you
Scores are an AI listener's judgment of the file, not readings from a calibrated meter or spectrum analyzer, so they will not give you exact loudness values or decibel figures. Results depend on the file you upload: a clip that was already compressed or converted will carry those artifacts into the rating. It is not a live microphone test, and it cannot see your hardware, so suggested causes (a charger, a ground loop) are informed guesses to check.
Frequently Asked Questions
Audio Quality Checker questions
How do I check audio quality of a recording?
Upload the file or record a sample, and the AI rates clarity, noise, distortion, dynamic range and frequency balance on a 0 to 100 scale. It then lists the specific problems it hears, how severe each one is, and what to do about them, so you get a verdict and a fix list in one pass.
Can I test my microphone quality with it?
Yes, indirectly. Record 20 to 30 seconds of normal speech with that microphone and upload it. The report tells you how the result sounds: noisy, thin, boomy, clipped or clean. It does not show a live input level meter, so use your system sound settings for that.
What counts as good audio quality?
For speech, good quality means the words are easy to follow, there is little background noise between phrases, nothing crackles or clips on loud syllables, and the voice sounds full without boom. For music, dynamic range and tonal balance matter more. The overall score summarizes how close your file gets.
Does it work for music as well as speech?
It works on both, and the same metrics apply. For a detailed engineering read of a song, such as stereo width, EQ between instruments and mastering loudness, the mix quality analyzer and audio mastering check are more specialized.
Can it fix the problems it finds?
No. It diagnoses and recommends; it does not edit or return a cleaned file. The recommendations point to the usual fixes, such as a pop filter, a low cut, noise reduction or re-recording in a different spot, which you apply in your editor or setup.
What does a quality check cost?
Each test uses credits from a monthly paid plan, like the other AI analysis tools. There is no trial tier; the pricing page has the details.
