Can this predict if my song will go viral?

No. It measures opening energy, tempo, average level and brightness. None of these predict how people will respond to a song.

Why is the tempo wrong?

The estimate is based on jumps in energy and is limited to 60 to 180 BPM. Songs without clear attacks, or at very slow or fast tempos, are often read at half or double speed.

What does opening energy mean?

It compares the level of the first 15 seconds with the level of the whole song. It does not judge whether the opening is a good hook.

Is my track uploaded?

Use the measurements, not the score

Opening energy is not hook quality. Tempo preferences vary by genre. Brightness and amplitude do not establish whether a song will connect with listeners.

How the acoustic snapshot works

How it works

Drop in a WAV, MP3, FLAC, M4A, AIFF or OGG file. It is decoded and mixed to mono in your browser, and nothing is uploaded. The tool then takes four simple measurements.

What it measures

Opening energy: the RMS level of the first 15 seconds compared with the whole song. A higher ratio means the start is louder than the song on average.
Tempo: an estimate from the spacing of energy jumps, kept between 60 and 180 BPM.
Energy: the average RMS level of the whole track.
Brightness: a rough proxy for how much high-frequency content the track has, taken from one short section.

What you get

Each measurement gets a score from 0 to 25 and a short label. The four add up to a total out of 100, shown with a band from lower to high heuristic score, plus a short list of things to check by ear.

Good to know

The total score is not validated. It cannot predict streams, virality, quality or how listeners will react.
The scoring prefers 120 to 150 BPM. That is a fixed rule in the tool, not a rule of music. A ballad at 70 BPM can be the right choice.
The tempo estimate can be off by half or double, especially on songs with soft attacks.
The brightness reading is an approximation, not a full spectral analysis.
