AcoustID News and Updates

Data Exports Restored

Mar 26, 2021
Daily JSON data exports are now available on https://data.acoustid.org/. They went down after the major problems on March 3rd. Monthly and yearly aggregates, including full data exports will be available later in Q2 2021. I’ll also try to make sure that we have readily usable tools for importing these data exports into a database.

Postmortem of the March 2, 2021 outage

Mar 5, 2021
On March 2, 2021, we had a large incident that led to the entire acoustid.org infrastructure going down. This will be the first of at least a few posts to explain what happened, how we got to this situation and what will happen in the future? I’ll not sugar-coat it, the most direct cause of the problem was the modern equivalent of the classic rm -rf / as root. With the classic one, you can only delete data from one server.

Chromaprint 1.4 released

Dec 3, 2016
A new version of Chromaprint has been released. This is a fairly big release I originally intended to call 2.0, but one key feature I was planning to include is not yet finished, so I decided to go with 1.4 instead. So what’s new? The biggest feature is that all components of audio fingerprinting process now work in a streaming fashion and can provide partial results at any time. That means that it’s now possible to feed a continuous audio stream to the process and get back partial fingerprints.

Five years of AcoustID

Oct 8, 2015
It’s hard to tell the exact date when the AcoustID project started, but if we go by the first entry in the database, it was October 8, 2010. That means project turned five this week! I thought it’s a good opportunity to gather some statistics from those five years. Back in 2010, we were starting from scratch. We had an empty database, while the solution that AcoustID was replacing (MusicDNS/PUID ) had fingerprints for 4.

AcoustID Demo API Key Changed

May 4, 2015
It seems that some people have been using the AcoustID demo API key from the documentation page for more than just testing, so it’s time to change it. If you were using the API key and your application stopped working, please register the application properly and get your own API key.

Chromaprint 1.2 released

Aug 26, 2014
A new version of Chromaprint has been released. This release doesn’t add any new features to the library, but there are some source code changes for better compatibility when building the library in non-standard situations. Because the functionality hasn’t changed, this a source code only release. You can use fpcalc binaries from version 1.1. Download: Source code tarball (517.2 KB) Changes since version 1.1: Fixed compilation with neither libswresample nor libavresample (#11) Fixed compilation with static libav (#10) Functions chromaprint_encode_fingerprint and chromaprint_decode_fingerprint are changed to accept const pointer as input Added support for using the Kiss FFT library (should make Android port easier) Removed obsolete dev tools from the package More compatible DEBUG() macro

Chromaprint 1.1 released

Nov 23, 2013
A new version of Chromaprint has been released. There are a few bug fixes, fixed compilation error on OS X 10.9 and added support for compilation with libav (FFmpeg is still the preferred library to use with Chromaprint). The official binaries have been build with FFmpeg 2.1. I have switched to a more automated build system for the binaries, so there might be new problems with them. If you find they do not work as expected, please let me know.
