Free Spectrum Analyzer For Mac + Windows
APU Software has introduced APU Spectrum Analyzer, a free spectrum analysis tool for Mac and Windows.
It supports a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 up to 65536) to suit your needs.
Quickly switch between standard dB ranges or auto-range and view the frequency spectrum in log, linear, or note-based scale. Supports histogram hold for measuring long term frequency response. You can also adjust the bucket size independent of the FFT size and take snapshots of the frequency response for reference.
APU Spectrum Analyzer is available now as a free download.
