Why does SunoToolkit provide integer BPM instead of decimals?

Most professional DAWs snap project grids to whole number tempos (e.g., 124 BPM instead of 123.87 BPM). Our detector intelligently analyzes beat transients and returns the true musical tempo, ready for instant import into your DAW project without drifting off-grid.

What musical scale formats and codes are provided by the Key Finder?

Our chromatic pitch profile analyzes root frequency distributions across the full track. It instantly outputs: Root Key & Mode (e.g., C Minor), Camelot Wheel notation (e.g., 5A / 8B for harmonic DJ mixing), Relative Major/Minor keys, and the exact 7 musical notes belonging to that scale.

How do I fix songs that cut off abruptly in Suno AI?

Upload your track to our Smart Outro Trimmer, inspect the waveform with multi-level zoom (up to 16x), adjust the end marker to cut unwanted trailing artifacts, and choose a natural exponential or linear fade-out duration (1 to 8 seconds).

Is the Audio Analyzer and Waveform Trimmer free to use?

Yes, both the BPM & Musical Key Detector and the Smart Outro Trimmer are 100% free with unlimited usage and no credit card required.
