What you get
Hit your loudness target
Read integrated LUFS for the whole song, with −14 and −23 LUFS markers on the meter.
Catch clipping early
4× oversampled true peak and an overs counter show inter-sample peaks before they reach your export.
Ten meters, four panes
Spectrum, spectrogram, goniometer, correlation, waveform, loudness, peak, stereo bands, resonance and waterfall, side by side.
Who it's for
Mix engineers and producers
Shows LUFS, true peak, phase and a spectrum on any track or the master bus while you mix, in up to four panes.
Independent artists
Confirms the integrated loudness and true peak of a final master before you send it to a distributor.
Podcasters and video creators
Measures a voice or a soundtrack against −14 and −23 LUFS markers and counts overs above −1 dBTP.
Music and audio students
Spectrogram, goniometer and waterfall views make frequency, stereo width and phase visible while a song plays.
When to use it
- You're about to export and want the integrated LUFS of the whole song
- A mix sounds thin or hollow in mono and you suspect phase
- Something rings or whistles in a track and you can't find the frequency
- You want a true-peak reading after mastering, beyond the mastering window's estimate
- You want to see how hot a generated song's peaks are before you master it
What you can make with it
Whole-song LUFS
Put Analysis One last on the master bus, press RESET and play from start to finish so the integrated reading covers the full song.
Overs before export
Watch the overs counter in Peak / RMS during the loudest chorus, and lower Mastering One's ceiling or Loudness if it climbs.
A mono safety check
Watch Correlation during wide sections; readings that sit near −1 warn that parts may cancel when the song plays in mono.
Find and notch a ring
Let Resonance list the narrow peaks with their note names, then cut the worst one with a Notch band in EQ One.
Width by frequency
Use Stereo Bands to check that the lows stay narrow while the highs spread wide.
The loudest section, found
Pair Waveform with Loudness in two panes to spot the section that clips or jumps in level.
A vocal's top end, seen
View a vocal on the Spectrogram to see where bright consonants flare before you reach for EQ.
A mix lesson in four panes
Show Spectrum, Goniometer, Loudness and Waterfall in a quad and watch each one change as instruments enter.
A moment held still
Press FREEZE to hold every pane on a moment, such as a clipped hit, while you take a closer look.
Analysis One is the online audio analyzer in Soundverse AI Studio: a metering plugin with 10 meters that you add to any track, or to the master bus to measure the whole mix. It's for producers and mix engineers who need to check loudness for streaming or broadcast, catch clipping and phase problems, and find harsh resonances before they master. It measures without changing your sound, uses no tokens and is free on every plan.
What you can do
The 10 meters
Pick one, or up to four side by side.
Spectrum
An FFT analyzer with peak hold that names its loudest frequency and the note.
Spectrogram
Frequency over time as a heat map.
Goniometer
The stereo field as a Lissajous display.
Correlation
Phase between left and right, from −1 to +1, with its history.
Waveform
Amplitude over time with clipping marked red, and zoom on both axes.
Loudness
Momentary, short-term and integrated LUFS, loudness range, and −14 and −23 LUFS markers.
Peak / RMS
4× oversampled true peak in dBTP, RMS and a count of overs above −1 dBTP.
Stereo Bands
How wide the sound is in each frequency band.
Resonance
Narrow peaks at least 7 dB above the spectrum around them, with note names and a top list.
Waterfall
A 3D spectrogram that scrolls as the song plays.
How it works
Add it to a track
In AI Studio, click the ⓘ button on a track's header to open Track Details, click ADD EFFECT and pick Analysis One under Meter. For the whole mix, open the Mixer and click FX on the MASTER strip first.
Open the window
Click the Analysis One slot to open its window, then float it, dock it to the right or go full screen.
Choose your meters
Pick a meter from the rail, or split the view into two, three or four panes and give each pane its own meter, such as Loudness beside Spectrum.
Play and read
Press Play and the meters update as the song plays. FREEZE holds the display while measuring continues, and RESET clears integrated loudness, peaks and histories.

Why use Analysis One
Loudness, measured properly
Momentary, short-term and gated integrated LUFS with loudness range, using K-weighting, with markers at −14 and −23 LUFS.
Peaks between the samples
True peak is measured with 4× oversampling, beside RMS and a count of overs above −1 dBTP, so inter-sample clipping shows up before you export.
The stereo field at a glance
A goniometer, a −1 to +1 correlation meter and Stereo Bands, which shows width per frequency band, help you spot phase and mono problems.
Find what rings
Resonance hunts narrow peaks that stand out from their neighbors and lists the top ones with note names, and Spectrum names its loudest frequency as a note too.

Good to know
Measures during playback
Readings build up as the song plays. Integrated loudness covers everything played since the last RESET.
One track at a time
Analysis One measures the track it sits on. Put it on the master bus, after Mastering One, to measure the final mix.
Window open to measure
It passes audio through untouched and measures only while its window is open.
Nothing to automate
Analysis One has no settings that change the sound, so there's nothing to automate.
Frequently asked questions
Is the Analysis One online audio analyzer free?
Yes. Analysis One is included on every Soundverse plan, including Free, and uses no tokens because it runs in your browser inside AI Studio. You can add it to any track or to the master bus. Your plan only changes the studio around it: on Free, a project holds up to 3 tracks and exports MP3, while Creator and above allow more tracks plus WAV, FLAC and stem export.
How accurate are Analysis One's LUFS and true-peak readings?
Analysis One measures loudness with K-weighting, a 400 ms momentary window, a 3-second short-term window, and absolute and relative gating for integrated loudness and loudness range. True peak uses 4× oversampling. For a final number, press RESET, play the whole song through, and measure on the master bus after any mastering, because integrated loudness covers everything played since the last reset.
Can I analyze any song with Analysis One?
You can measure any audio you have the rights to bring into a Soundverse AI Studio project, such as your own mixes, stems, recordings and Soundverse results. Analysis One only reads the audio; it doesn't change it. On the Free plan, what you make in AI Studio is for personal use; paid plans include a commercial license, and the Pricing page lists what each plan covers.
What can't Analysis One do?
Analysis One measures audio as it plays in Soundverse AI Studio, so it can't scan a file faster than real time, and it doesn't save or export a report. It measures only the track it sits on, and only while its window is open. It never changes the sound: to fix what you find, use EQ One, De-Esser One or Mastering One.
What is Analysis One?
Analysis One is the metering plugin in Soundverse AI Studio: one plugin with 10 meters, from a spectrum analyzer and spectrogram to LUFS loudness, true peak, phase correlation and a resonance finder. You add it to a track or the master bus, and it measures that audio live in your browser while the song plays. It's a measurement tool, not an AI model.
Which meters does Analysis One include?
Analysis One has 10 meters: Spectrum (an FFT analyzer), Spectrogram (frequency over time), Goniometer (the stereo field), Correlation (phase from −1 to +1), Waveform (amplitude over time, with clipping marked red), Loudness (LUFS), Peak / RMS (true peak in dBTP), Stereo Bands (width per band), Resonance (a peak hunter) and Waterfall (a 3D spectrogram).
How do I check my song's loudness in LUFS?
Open the Mixer in Soundverse AI Studio, click FX on the MASTER strip, add Analysis One and open its window. Pick Loudness, press RESET, then play the song from start to finish. The I value is the integrated loudness for the whole pass, with momentary (M) and short-term (S) readings above it and the loudness range (LRA) below, against −14 and −23 LUFS markers.
Can I see several meters at once?
Yes. Analysis One can show one meter, two side by side, three in a row, a 2×2 quad or four in a row. Click a pane, then pick its meter from the rail, for example Loudness, Spectrum, Goniometer and Waterfall in a quad. FREEZE holds every pane while measurement keeps running in the background.
Ready to see what your mix is doing?
