Cyanite API Update – New Instruments and More

May 12, 2021
Cyanite API update

We are proud to announce the latest API update. This update includes 8 new instrument classifiers, improved BPM, Key, and Time Signature detection, and improved Similarity Search.  For details, see full documentation here:

Now let’s take a closer look at it!

New Instrument Classifiers

Now, additionally to our percussion classifier, we expose the synth,  piano, acousticGuitar,  electricGuitar, strings, bass, bassGuitar and brassWoodwinds classifiers.

We also deprecated the AudioAnalysisV6Result.instruments field.

The new field AudioAnalysisV6Result.instrumentTags exposes a list of detected instruments throughout the track.

New Key and BPM classifier

The FullScaleMusicalAnalysis and FastMusicalAnalysis types are now deprecated and will be removed from the API on 15 June 2021.

The new AudioAnalysisV6Result.key and AudioAnalysisV6Result.bpm expose improved key and bpm values over the now deprecated FullScaleMusicalAnalysis and FastMusicalAnalysis.

New Time Signature Classifier

The AudioAnalysisV6Result.timeSignature now exposes the time signature of the track (e.g. 3/4 or 4/4) as a string.

New Improved Similarity Search

We improved the performance of our similarity search based on audio features. In addition to that, we exposed a new single field that allows searching similar tracks for both library and Spotify tracks with additional filters for bpm, key, and genre.
