In their own words
ACRCloud
ACRCloud provides audio recognition services for files, streams, and live broadcasts. Its music recognition uses a fingerprint database of more than 150 million tracks, and results can include links to Spotify, Apple Music, Deezer, and YouTube, as well as ISRC and UPC codes. Other listed capabilities include metadata, AI music detection, broadcast monitoring, cover song identification, second-screen sync, copyright compliance, audience measurement, humming recognition, offline recognition, and speech to text. Teams can assemble workflows with APIs, SDKs, console tools, and documentation. Mobile SDK references cover iOS, Android, and Unity; its Go SDK supports Linux and macOS. The service is aimed at music services, broadcasters, labels, distributors, advertisers, automotive platforms, brands, and rights organizations. Distributors can compare user-generated content with the music database to identify copyright infringement risk. The platform supports Android, iOS, Linux, macOS, web, and Windows. The listed trial is free for 14 days, with full API access and no credit card required.
Voxengo SPAN
Voxengo SPAN is a free real-time FFT spectrum analyzer plugin for audio and music production applications. It analyzes stereo, mono, mid-side, and surround signals, including 5.1 and 7.1, and can display spectra from two channels or channel groups at once. Metering includes EBU R128 and K-system readings, RMS and true-peak measurements, clipping detection, and stereo correlation. Users can adjust FFT block size, window overlap, visual slope, smoothing, and a secondary spectrum display. Other functions include output power statistics, channel routing and grouping, presets, undo and redo, and A/B comparisons. SPAN is available for Windows and macOS in VST, VST3, and AAX formats, with AudioUnit also listed for Mac. The maker lists Windows XP and later and macOS 10.12 and later, with a 2.5 GHz dual-core or faster processor and at least 4 GB of RAM. Spectrum import and export for track comparisons is a SPAN Plus feature; the free plugin workaround works only in some hosts.
