One important change on the website is addition of email and website fields to applications. If you are an author of an open source application that uses the AcoustID API, please fill them in so that I can contact you in case there is a problem with your API key. These fields are not displayed anywhere publicly.

Contributor statistics were also removed from the website. They were interesting when the project was small and had a couple of contributors, but recently I’ve had a increasing number of people asking to had their account removed from the statistics, so I’ve decided to remove the statistics completely.

The /v2/lookup method supports a new option sources in the meta parameter. It’s only applicable when meta includes also recordings and it tells the server to return also the number of sources for each returned recording (corresponding to the Sources field on the website).

There are also two new methods /v2/user/lookup?user=X and /v2/user/create_anonymous?client=X&clientversion=X, to support anonymous user accounts. They can be used from applications that can’t ask the users to log in on the Acoustid website, but there are a number of rules that such applications should follow:

• The returned API keys must be stored in the user’s settings and re-used. Do NOT create a new API key every time the application is started.
• You can’t assume the saved API key still exists. Unused anonymous accounts will get deleted after some time. Use the user lookup call to verify the API key still exists.

Changes since version 0.4:

• Unicode filename support on Windows.
• Support for 24-bit sample formats.
• Reading MBID tags from foobar2000-written MP3 files.
• Added .desktop file for Linux.

  • Linux, 64-bit (689K)

Changes since version 0.5:

• Support for 24-bit file formats in fpcalc.
• The fpcalc utility now uses 120 seconds of audio data by default.
• Python bindings moved to a separate project (pyacoustid).

Some time ago I added overall search statistics. This release adds similar statistics for individual applications. For example:

Of course, these statistics are only available to the owners of the applications.

Another change related to external application support is that the submission API call now accepts a new parameter clientversion. This is the first step to allowing a single application API key to be used by multiple versions of the application. In following releases I’ll be changing the API key structure to allow applications to have a number of API keys that can be disabled/enabled any time.

  • Mac OS X, x86, 10.4+ (524K)
  • Linux, x86 (651K)

Changes since version 0.4:

• Unicode command line handling in fpcalc.
• Fixed a crash in fpcalc when FFmpeg was not able to identify the codec.
• Added encode_fingerprint to the Python bindings.

Here is a complete list of changes in this release:

• Faster and more robust way of comparing fingerprints.
• Mapping of fingerprints to PUIDs.
• Initial support for storing custom foreign IDs.
• Better tracking of the source for each fingerprint and fingerprint<->ID mapping.
• Tracks now have UUIDs attached to them, so the default result ID format will change in a future version of the web service.

Changes since the last version are:

• New icon:
• HTTP proxy support using the $http_proxy environment variable
• Support for reading PUIDs from tags
• Fixed submission of the file format

You can download the new version on the Acoustid website.

I’ve also released a new version of the Acoustid fingerprinter, which can utilize this new functionality and if your files don’t have MBIDs embedded in tags, it will send the metadata it can find in tags, instead of completely skipping the files. You can download the new version here:

• Windows Application
• Mac OS X Application
• Source Code Tarball

Note that this is the first time I actually built the fingerprinter on OS X, so if the package doesn’t work for you, please let me know. It should work on Intel Macs with OS X 10.4 or never.

Changes since version 0.3:

• Support for building a Mac OS X framework.
• Support for building a static library.
• Simple C example (fpcalc) that can be used from external applications for fingerprint calculations.
