What it does
As a DJ, I got tired of record pool tracks that looked like WAVs but were actually upscaled MP3s. On a proper sound system, the high-end distortion is obvious. So I built Spectro: a macOS app that instantly tells you if a file is Lossless, Lossy, or Fake Lossless. Batch analysis, Finder integration, Quick Look support, and 100% offline. Perfect for checking unreleased promos before a gig. $39 one-time purchase.
Spectro detects fake lossless audio on Mac. Scan WAV, AIFF, FLAC, MP3, and AAC files to find compressed tracks in disguise, fully offline.
Spectro tells you exactly which WAV, AIFF, and FLAC files in your library are actually compressed MP3s in disguise. Drop your Beatport or Bandcamp downloads and get an instant verdict - before you play them on a professional system. Online stores, promo channels and Bandcamp uploads are full of MP3s upscaled and renamed to FLAC, WAV or AIFF. The file size goes up. The audio inside doesn't. Spectro reads the actual waveform with a full FFT, like a luthier tapping wood. ~128 kbps MP3 in a FLAC wrapper. Brick wall at 15.9 kHz. Only hiss above the line. You paid for nothing. Energy reaches the Nyquist ceiling at 22.3 kHz. Air, transients and shimmer survive intact. This is what you bought.…from getspectro.app

I'm a huge datahoarder and have always appreciated tools / services like PureRef and Are.na which help me make sense of everything I collect. Those services concern themselves with images and video - I wondered, why can't the same be done with music and audiofiles? I actually got the inspiration for the filenaming scheme from the Emacs Denote package - every sample is saved in the…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
