Question 1

What is ShredForge?

Accepted Answer

ShredForge is a web-based guitar technique training platform. It provides structured practice tools (Scale Builder, Stretch Rack, Rhythm Lab), a Skill Tree that tracks your speed progression in Notes Per Second, and real-time audio analysis that measures your timing accuracy and cleanliness.

Question 2

Is ShredForge free?

Accepted Answer

Yes, ShredForge has a free plan that includes unlimited exercise creation, the Scale Builder, Stretch Rack, Rhythm Lab, Session Builder, Community access, and basic Skill Tree progression. The Pro plan (€4.99/month or €49.99/year) unlocks unlimited audio analysis, unlimited Skill Tree levels, full stats history, and leaderboard submissions.

Question 3

How does the audio analysis work?

Accepted Answer

ShredForge uses your browser's Web Audio API to capture your guitar signal through your microphone or audio interface. All processing happens locally in your browser — your audio never leaves your device. The system detects note onsets, measures timing deviations against the expected grid, and gives you cleanliness and tempo stability verdicts.

Question 4

What is NPS and why does ShredForge use it instead of BPM?

Accepted Answer

NPS stands for Notes Per Second. Unlike BPM, which changes meaning depending on the subdivision (16th notes at 120 BPM = 8 NPS, triplets at 120 BPM = 6 NPS), NPS directly measures how fast your hands are moving. This lets you compare speed across different exercises and subdivisions fairly.

Question 5

Does ShredForge work on mobile?

Accepted Answer

Yes, ShredForge is fully responsive and works on mobile browsers. However, for audio analysis, a desktop browser with a proper audio interface will give the best results due to lower latency.
