Mureka Try it →Watch full video →Jorge Albuquerque · Jun 2026

Demo summary

Using Spectrum Thief, the user performs a direct frequency comparison between the original guitar recording and the Mureka AI extraction to visualize energy loss.

Step-by-step

Open Spectrum Thief to analyze both signals
Set the target for the blue line to the original guitar recording
Set the orange line to the Mureka extracted stem
Compare the frequency curves, specifically looking at the low end below 250 Hz

Watch out for

The extracted stem shows lower energy levels below 250 Hz compared to the original

Tips

Use spectrum analysis to visualize exactly where energy or 'body' is being lost during AI extraction

Highlights

“from around 250 upwards, the curves are surprisingly close”
