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.
Blue Cat's FreqAnalyst
Blue Cat's FreqAnalyst is a free plug-in for monitoring the spectral content of mono or stereo audio in real time. It displays spectrum, instant curve and peak curve views, with continuous changes rendered using smooth interpolation. Users can zoom the display, choose among sizes and set absolute or relative thresholds. The interface supports skins, transparency and zoom customization, while MIDI control, automation and MIDI Learn provide ways to control the plug-in. A preset manager is included, and users can copy and paste a plug-in state between instances. FreqAnalyst is not a standalone app: it requires a compatible audio host and is available in VST, VST3, AAX and Audio Unit formats for macOS and Windows. The stated operating systems are macOS 10.9 or newer and Windows Vista, 7, 8, 10 or 11. It supports up to two channels. The maker says processing stops when the input is silent, so it uses no CPU while idle.
