Audio Codec / Encoding
Encoding is the process of changing digital audio from one format to another, typically from uncompressed audio to one of the compressed formats. The compressed formats have two broad categories – lossless and lossy. Lossless audio can be decoded back into the exact uncompressed audio, while lossy formats may remove up to 90% of original digital data for maximum space reduction. The two most common lossy formats are AAS and MP3.

Audio Bandwidth
The range of audio* frequencies which directly influence the fidelity of a sound. The higher the audio bandwidth, the better the sound fidelity. The highest practical frequency which the human ear can normally hear is 20 kHz. An audio amplifier which processes all frequencies.

Audio Dub
Result of recording over prerecorded videotape soundtrack, or a portion, without affecting prerecorded images.

Audio Frequency Modulation
(AFM) Method of recording hi-fi audio on videotape along with video signals.

Audio-Follow-Video
During video recording, the video signal is usually accompanied by an audio signal. Sometimes, during video editing*, it is often necessary to separate the audio from the video signal. Audio-follow-video mixers allow accompanying audio to "follow" the video when switching video sources or not. The Digital Video Mixer provides either function.

Audio Mixer
Device with user-adjustable controls to blend multiple sound inputs into desired composite output.

BPM / Tempo
The speed or pace of a music track measured in beats per minute (BPM). Thus, 120 BPM means 120 beats per minute.

Metronome pulse which assists musicians in playing in time. When you see that a particular music track was “recorded to a click track” it basically means it was recorded with steady tempo that does not change throughout the track.

Clipping
Distortion that occurs when audio signal attempts to exceed the maximum level which the recording equipment can handle.

Content ID
YouTube employs a robust system called Content ID that allows copyright owners to identify and to manage how their content is used on YouTube. Every video uploaded to YouTube is scanned against the Content ID database to detect if it contains any copyrighted music or video. If there is a match, the user who uploaded the video receives a copyright claim.

Copyright

However, even though the music under the Creative Commons license is free to download and to use, there may be limitations that affect how you can use the music in your project. Most common limitation is attribution, which means that you must credit the author, Share-Alike, which means that you must distribute your work under the same terms, and Non-Commercial Use.

Decibel
Measure of audio signal strength based on a logarithmic scale. Also the unit of measure for sound pressure level

Digital Fingerprinting
A digital fingerprint is a digital summary generated from an audio file. Fingerprinting is used to identify songs and sound effects and to monitor their usage. YouTube uses digital fingerprinting system called Content ID to prevent copyright violations.

Dubbing / Overdubbing / Voiceover

Synchronization (Sync) License
Sync license grants the right to use a music composition (however, NOT the recording of the composition) in a video or a movie. “Synchronization” in this context means using the composition in synchronization with the picture on screen.

Sample Rate
The number of times an A/D converter samples the incoming analog waveform each second measured in Hz or kHz. For example, 44 100 samples per second can be expressed as 44.1 kHz for a CD quality WAV file.

Stems
When mixing a music recording, stems can represent, for example individual sub-mixes for a rhythm section, all lead instruments, backing vocals, lead vocals — or any other combination that suits the particular project. Stems help video producers to create customized audio soundtracks by adding or removing individual musical elements as needed. For instance, you might want to remove the lead instruments from the mix to leave more sonic space for the dialogue.
