Spek alternative for macOS
A Spek Alternative Built for Modern macOS
If you used Spek before, Spectro gives you the same core visibility plus actionable verdicts and batch workflows for real DJ library cleanup.
In short
Spectro keeps spectrogram clarity, but adds automatic FAKE/MEDIUM/LOSSLESS verdicts and batch workflows. Its detection method is backed by peer-reviewed research (ACM MM&Sec 2009) achieving 99% accuracy across 2,512 songs.

FAQ
Why not just use Spek for free?
Spek hasn't been updated since 2013 and runs on Apple Silicon only through Rosetta 2 emulation. More importantly, Spek shows you a spectrogram — you still have to decide if a file is fake or not. Spectro makes that call automatically.
Does Spectro show the spectrogram like Spek does?
Spectro shows the frequency cutoff and diagnostic data per file. The focus is on the verdict and the cleanup workflow rather than a full visual spectrogram view.
Can I try Spectro before buying?
Yes. The first 100 tracks are free, no account required. Run it on a real set folder and see how many files come back FAKE or MEDIUM.
Is Spectro subscription-based?
No. One-time purchase at $39. No renewals, no account required after activation.
