How to read the analysis
BPM and key are estimates. Loudness, peaks and spectrum help you compare versions and decide what to review in the mix.
Is the BPM half or double what I hear?
A result of 70 BPM can describe a pulse you count at 140. Check the tempo against the rhythm you hear; automatic analysis does not replace that decision.
Is the detected key definitive?
It estimates the main key. Key changes, modal scales and material without clear pitched notes may need musical review.
Does this approve my song for streaming?
No. Loudness values provide references for comparing levels. They do not certify artistic quality or acceptance by a platform.
