What is Traktomizer for?
Traktomizer Audio Analyser software for OS X accurately measures danceability, acousticness, instrumentalness, valence, duration, energy, key, liveness, loudness, speechiness, tempo and time signature, for songs, tracks or passages of all kinds of music and speech.
Levels for anger, relaxation, happiness, sadness, masculinity and femininity, are measured and rated according Std. ground-truth SVM models.
Genre and sub-genre are also identified and reported together with 13 opportunistic neighbours for an ordered tally of 15 genres most likely to generate more song plays.
The main goal for Traktomizer is to extrapolate a reliable and useful response about the commercial viability of a premaster mix, usually during the final stages of production editing, so that the Producer(s) may be alerted to crucial audio optimization opportunities, the adjustments of which are expected to significantly-positively affect play-list inclusions and discoverability on all major streaming platforms like Spotify, Apple Music, Google Music, Pandora and hundreds of others.

What Kinds of Audio Features does Traktomizer measure?
float: confidence the track is “acoustic” (0.0 to 1.0)
float: relative danceability (0.0 to 1.0)
float: length of track in seconds
float: relative energy (0.0 to 1.0)
int: between 0 (key of C) and 11 (key of B flat) inclusive
float: confidence the track is “live” (0.0 to 1.0)
float: overall loudness in decibels (dB)
int: 0 (major) or 1 (minor)

Measurements that include DC component:
DC_offset = mean(signal)
bitrate = DC_offset = mean(signal)
Maximum/minimum sample value
Estimate of true bit rate
Measurements that don’t include DC
A-weighting filter to the signal
weighted = A_weight(signal, sample_rate)
weighted_level = rms_flat(weighted)
Chart overlay of dB Values for two songs at a time. (not functional since 07 Jan 2017 as is being upgraded)
int: the number of audio channels used during analysis
int: the sample rate used during analysis
audio decoder used by the analysis (e.g. ffmpeg)
float: confidence that key detection was accurate
dict: other track metainfo (bitrate, album, genre, etc.)
float: confidence that mode detection was accurate
the audio sample rate detected in the file
float: confidence that tempo detection was accurate

Is Traktomizer a VST or Audio Unit Plugin?
Do I need to pay for accessing API data?
Do I need a Spotify Artist and or Next Big Sound account?
A Spotify Artist Account is recommended but Traktomizer will analyze audio with or without one.
Also, Spotify does not need to be available in your country for Traktomizer to work properly, except that we may not be able to produce benchmark playlists for you.
If you do not have a Spotify Artists and or Next Big Sound Account (which are both free), Traktomizer will eliminate some dependant calculations such as your Artist Hottness Rating compared to Benchmark Artists.
