Studio Glossary

Don’t know what a “stem” is? “DAW” sounds like a curse word? This glossary explains the most important terms you’ll hear in a recording studio.


Digital audio connection transmitting 8 channels over one optical cable. Used to expand interfaces with additional inputs.

Recording dialogue for film after filming is complete. The actor synchronizes voice with the image. Also known as: dubbing, looping. We offer ADR →

Recording parameter changes over time. E.g., vocal volume rises in the chorus — that’s volume automation.

Plugin for pitch correction. Used subtly (correction) or aggressively (T-Pain effect). At Flightcore, it works in real-time thanks to FPGA.


How many bits are used to record each audio sample. 16-bit = CD, 24-bit = studio standard. More = better quality, larger files.

Tempo of a track measured in beats per minute. 60 BPM = one beat per second. Trap: 140-160 BPM, pop: 100-130 BPM.

Exporting a project to an audio file (WAV, MP3). “Bounce it” = export it.

Virtual channel collecting signal from multiple tracks. E.g., “vocal bus” = all vocals go to one channel where they can be processed together.


Distortion — signal exceeds maximum level and gets cut off. Sounds like distortion. Avoid.

Choosing the best fragments from multiple recordings (takes) and assembling them into one perfect vocal. We do this during sessions with an engineer →

Reduces the difference between quiet and loud parts. Quiet becomes louder, loud becomes quieter. Basic mixing tool.


Software for recording and music production. Examples: FL Studio, Ableton Live, Logic Pro, Pro Tools, Cubase, Studio One, Reaper.

Relative unit — alone it doesn’t say much, needs a reference point. That’s why you’ll see different suffixes after “dB”:

  • dBFS (Full Scale) — in digital, 0dBFS is maximum level before clipping
  • dBu — in analog equipment, reference to voltage (0.775V)
  • dBSPL — acoustic pressure, how many decibels in the air

General rule: -6dB is roughly half as quiet, +6dB is roughly twice as loud.

Echo effect. Sound repeats with a delay. Different types: slapback (short), ping-pong (left-right), tape delay (analog character).

Sound without effects. “Send me dry vocal” = vocal without reverb, delay, etc.


Adjusts the volume of individual frequencies. You can boost bass, cut harsh highs, remove “boxy” mids.

Saving a project to an audio file. Synonyms: bounce, render.


Slider controlling channel volume. Physical on a mixer, virtual in a DAW.

  1. Audio feedback (unpleasant squeal)
  2. Information from the engineer (“give more energy”)

Programmable chip in some audio interfaces. Allows processing effects (Auto-Tune, compression) with minimal latency — faster than through a computer.


Signal amplification. “Add gain on the vocal” = make it louder at the input.

Effect that mutes signal below a set threshold. Used to remove noise between vocal phrases.


Mix sent to the artist’s headphones during recording. May be different from what the engineer hears.

Volume reserve before clipping. “-6dB headroom” = peak doesn’t exceed -6dBFS, leaving 6dB of reserve.

Filter that passes high frequencies, cutting lows. Used to remove rumble and unwanted low frequencies.


Input — where you connect a microphone or instrument.

Device connecting microphones/instruments to a computer. Converts analog signal to digital and vice versa.


Delay between playing a sound and hearing it in headphones. Lower is better. FPGA gives the lowest latency.

Type of compressor with high ratio, controlling maximum signal level. Brickwall limiter (∞:1) completely blocks signal above threshold.

Loudness unit used in streaming. Spotify normalizes to -14 LUFS.


  1. Final, mastered track ready for publication
  2. Master bus = main channel through which the entire mix passes

Final production stage — optimizing loudness and sound before publication. More → | Our service →

Protocol transmitting note information (not sound). Allows controlling synthesizers and virtual instruments.

Process of combining all tracks into a cohesive song. More → | Our service →

  1. Studio speakers (monitors)
  2. What you hear during recording

One audio channel. Opposite of stereo.

Multiple tracks separately. “Send multitrack” / “send trackout” = send all tracks separately, not one mix.


Output — where you connect speakers or headphones.

Recording a new track over an existing recording. First you record the beat, then you “overdub” vocals.


Sound position between left and right channel. Pan 100% L = only left headphone.

Loudest point of signal. “Peak -3dB” = loudest moment reaches -3dB.

Power for condenser microphones provided by interface or mixer.

Sound height. “Pitch correction” = fixing off-key notes.

DAW add-on — effect or virtual instrument. VST, AU, AAX, CLAP are plugin formats.

Amplifies weak microphone signal to working level. Preamp quality affects the sound.

Preliminary mix before finalization. Demo showing direction, not yet finished.


Space effect — simulates sound reflections in a room. From small room to large cathedral.

Natural sound of a room — AC hum, wall reverb. Recorded as “silence” for editing.


  1. Single audio sample in a digital file
  2. Fragment of recorded sound used in production (e.g., drum samples)

How many samples per second are recorded in a file. 44.1 kHz = 44,100 samples/s (CD standard), 48 kHz = video standard.

Gentle distortion adding warmth and character. Simulation of analog equipment.

Routing signal to an effect (e.g., reverb) without affecting the original track.

  1. Meeting in the studio — what does the first session look like? →
  2. DAW project file with all tracks

Controlling an effect with signal from another track. E.g., compressor on bass reacts to kick — bass makes room on each hit.

Single track or group of tracks exported to a separate file. “Vocal stem” = all vocals in one file. How to prepare stems →

Two audio channels — left and right. Standard playback format.


Single recording. “Let’s do another take” = let’s record again. During a session, we record many takes, from which we create a perfect comp.

Speed of a track, measured in BPM.

Single channel in a DAW project. One song can have 5-50+ tracks.


Equipment chain through which voice passes: microphone → preamp → compressor → EQ → interface.

Loudness.


Lossless audio format. Standard for studio work. Larger than MP3, but without quality loss.

Sound with effects. Opposite of dry.
