1) A range of frequencies, often identified by the center frequency of the range. 2) A group of musicians playing together.
A device, circuit or plug-in that allows a narrow band of frequencies to pass through the circuit, rejecting or attenuating frequencies that are either higher or lower than the specified range.
A device, circuit or plug-in that attenuates a narrow band of frequencies in the signal, allowing frequencies outside the band to pass. The exact opposite of a band pass filter.
(Sometimes abbreviated “Track“) A mixdown of a song minus the lead vocal and/or background vocals. In other words, a mixed track containing only the instrumental parts of the song.
In signal processing, bandwidth refers to the usable frequency range of a communication channel, measured by the difference between the device’s highest and lowest usable frequencies.
1) A collection of sound patches, sequencer data and/or operating parameters of a synthesizer’s generators and modifiers in memory. 2) A group of sound modules as a unit.
In music notation, bar is another term for measure—a specified period of time containing a certain number of beats, and marked by bar lines on each side of the written measure.
A microphone placement technique in which a microphone is placed close to a reflective surface. When done correctly, barrier miking ensures that both the direct and reflected sounds reach the microphone simultaneously, preventing phase cancellation between the two.
The first audio recording session for recording the basic tracks that serve as the song’s foundation (for example, the drums and bass).
The lower range of audio frequencies up to approximately 250 Hz. A reference value.
A type of loudspeaker cabinet design in which a port (opening) in the speaker cabinet enhances bass frequencies. The principle is that the sound pressure generated by the back of the speaker cone inside the cabinet is routed out the port at the front of the cabinet, mixed with the sound coming from the front of the woofer. Changing the port size and position will greatly change the character of the low frequencies.
A phenomenon found in loudspeakers in which higher frequencies are projected straight out of the loudspeaker, rather than dispersing along with the lower frequencies. When you stand on-axis in front of the speaker, it sounds as though it is only reproducing the high frequencies, rather than the mids or lows. This phenomenon is alleviated by routing the high frequncies through horns in the loudspeaker.
1) The steady, even pulse in music. 2) The action of two sounds or audio signals of slightly different frequency interfering with one another and causing periodic increases and decreases in volume, heard to the ear as “beats.”
The process of adjusting the tempo variations in a recorded piece of music to fit the set tempo of the project. In a DAW, this is done using time stretching tools and cuts to synchronize the transients to the appropriate tempo markers. This technique is often used, for example, to reconcile a drum or bass performance that was recorded without a click track.
A technique predominantly used by DJs to synchronize the tempos of two recorded tracks, generally through the use of time stretching and pitch shifting tools, to create a seamless transition from one song into another.
