Traktomizer Frequently Asked Questions (FAQ)

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.

crest_factor

A-weighting filter to the signal
weighted = A_weight(signal, sample_rate)
weighted_level = rms_flat(weighted)

Is Traktomizer a VST or Audio Unit Plugin?
No. Traktomizer is a stand-alone Apple-OSX application only. Works to make a plugin version available are underway. In the meantime, you are welcome to register your interest for the plugin version by submitting a support ticket.

Do I need to pay for accessing API data?
No, your purchase of Traktomizer includes access to all API data used by the application.
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.

Is there a trial version of Traktomizer
Yes, we provide a fully-featured 7 day trial software version which will allow you to analyze up to 5 songs.

Note that we limit our trial to 5 songs so that you can evaluate the software while having minimum impact on our paid users – because Traktomizer utilizes API data which itself is limited to number of queries per second.

What updates will I receive?
Users receive lifetime free updates with their purchase of Traktomizer which includes all minor and major versions.

This is to ensure our users are kept abreast of a very fast-changing music industry and the various data that may become available from the APIs with which Traktomizer integrates.

What type of support do I get?
We support our users with direct email and a Support Ticket System for questions, problems, suggestions, comments etc.

We usually reply to support tickets in less than 12 hours and no more than 24 hours, depending on current ticket volumes.

Support tickets are available at https://traktomizer.com/submit-support-ticket

We also update our website with supportive information, key issues, advice and learning as and when such information becomes available.

You can also opt-in to our free email newsletters which provide supportive information, ideas, advice and suggestions.

Why is my sofware download link time-limited?
To protect your investment and ours we time-bomb download links.

If you are unable to download your software package within the time frame, simply contact support and we will immediately provide a new link for you.

We securely provide Traktomizer download links (i.e. https)

Can I resell or transfer my licence to a third party?
Yes, but you must contact us with the contact details of the new software owner so that we can provide them with a new Activation Code.

By selling or transferring your Traktomizer software, you understand your rights and license to use Traktomizer will be revoked.

Can I give a copy of to my band members or Mastering Engineer?
Yes, we want your band to benefit from Traktomizer.
