How to find zero-crossing points for perfect loops
A zero-crossing is where the waveform passes through the zero line — cutting a loop there avoids the sudden level jump that causes a click. Finding matching zero-crossings by hand is fiddly. Loop Music locates and aligns them automatically, so your loops are click-free without any waveform surgery — in about 20 seconds.

Zero-crossing loops: common questions
What zero-crossings are and why they matter.
How do I find zero-crossing points for a loop?
Let Loop Music do it — it locates matching zero-crossings and aligns the ends automatically, so the loop is click-free without you hunting through the waveform.
By hand you'd zoom in on both ends of the loop and place cuts exactly where the wave crosses zero, which the algorithm automates.
What is a zero-crossing, and why does it stop clicks?
It's the point where the waveform passes through zero amplitude. Cutting there means no sudden level jump at the join, so there's no click — and Loop Music aligns both ends to matching crossings.
A click happens when the loop jumps from one non-zero level to a different one; matching zero-crossings removes that jump.
Do I need audio-editing skills for this?
No. Loop Music handles the zero-crossing alignment for you, so you get a click-free loop without any waveform editing.
This is the tedious part of looping in a DAW, and it's exactly what the tool automates.
Is it free?
Yes — Loop Music's free plan includes five seamless loops a month, and each takes about 20 seconds to make.
Pro adds WAV export and a higher limit if you make loops often.
