Spek
Spek is a free audio spectrogram analyser for macOS that visualises the frequency content of audio files in real time. It displays spectrograms for WAV, FLAC, Ogg Vorbis, Opus, MP3 and other formats, helping audio engineers, music producers, and sound designers inspect the frequency distribution, identify noise, detect compression artifacts, and verify audio quality. The app is lightweight and particularly useful for quality control during mastering and for diagnosing audio issues.
AI Recommendation
1 suggestionWe could not confirm whether a native Apple Silicon build of Spek exists — the available search results do not contain clear architecture information, and the project's visibility appears limited. If you rely on Spek for audio analysis, the most practical step is to contact the Spek project directly through its GitHub or homepage to ask whether a native build is planned, since Apple is removing Rosetta 2 in macOS 28 (September 2028) and an Intel-only build will stop launching on that release. As an actively maintained alternative with confirmed native Apple Silicon support, consider AudioKit, SpeakLine (built into macOS), or Audacity — all can display spectrograms and run natively on M-series Macs. For professional mastering work, Wavelab or izotope's RX are industry-standard tools with native builds.
