AES53 is a standard first published in October 2006 by the Audio Engineering Society that specifies how the timing markers specified in AES47 may be used to associate an absolute time-stamp with individual audio samples.
 AES47 specifies a format for the transmission of digital audio over asynchronous transfer mode (ATM) networks.
 A recommendation is made to refer these timestamps to the SMPTE epoch which in turn provides a reference to UTC and GPS time.
 It thus provides a way of aligning streams from disparate sources, including synchronizing audio to video, and also allows the total delay across a network to be controlled when the transit time of individual cells is unknown.
 This is most effective in systems where the audio is aligned with an absolute time reference such as GPS, but can also be used with a local reference.
Freesound is a collaborative repository of Creative Commons licensed audio samples with more than 230,000 sounds and 4 million registered users (as of February 2015).
 Sounds are uploaded to the website by its users, and cover a wide range of subjects, from field recordings to synthesized sound effects. Audio content in the repository can be tagged and browsed by folksonomic means as well as standard text-based search.
 Audio content in the repository is also analysed using the open-source audio analysis tool Essentia, which powers the similarity search functionality of the site.

In professional audio, a digital mixing console (DMC) is an electronic device used to combine, route, and change the dynamics, equalization and other properties of multiple audio input signals, using digital computers rather than analog circuitry.
 The digital audio samples, which is the internal representation of the analog inputs, are summed to what is known as a master channel to produce a combined output.
 A professional digital mixing console is a dedicated desk or control surface produced exclusively for the task, and is typically more robust in terms of user control, processing power and quality of audio effects.
 However, a computer with proper controller hardware can act as the device for the digital mixing console since it can mimic its interface, input and output.
