A routing option that sends a copy of a channel's audio to another destination (like a reverb or delay) while keeping the original signal intact. Also called aux send or send.
A digital distortion effect that reduces the bit depth and/or sample rate of audio, creating a lo-fi, gritty, or retro digital sound. Popular in electronic and experimental music.
Beats Per Minute - the measurement of tempo in music. For example, 120 BPM means 120 quarter note beats occur in one minute. House music typically sits at 120-130 BPM, while trap is usually 130-150 BPM.
A channel that combines multiple audio signals together. Commonly used for grouping similar instruments (like all drums) for collective processing or to organize a mix.
A modulation effect that creates a thicker, richer sound by duplicating a signal and slightly detuning and delaying the copies. Makes a single voice sound like multiple performers.
Digital distortion that occurs when audio exceeds 0 dBFS, causing the waveform peaks to be cut off. Results in harsh, unpleasant distortion and should generally be avoided in digital audio.
A dynamic processing technique that reduces the volume difference between the loudest and quietest parts of audio. Used to control dynamics, add punch, or create consistency in a mix.

A control that balances the original unprocessed signal (dry) with the effected signal (wet). At 0% wet, you hear only the original; at 100% wet, you hear only the effect.
A processor that adjusts the balance of different frequency ranges in audio. Used to shape tone, remove unwanted frequencies, or make instruments sit better in a mix.
Learn more: EQ FundamentalsA modulation effect similar to chorus but with a more extreme, jet-plane swooshing sound. Created by mixing a signal with a delayed copy where the delay time varies.
The practice of managing signal levels at each stage of the audio chain to maintain optimal signal-to-noise ratio and prevent distortion. Critical for clean, professional mixes.
A processor that mutes or reduces the volume of audio below a certain threshold. Used to remove background noise, tighten drum sounds, or create rhythmic effects.
The amount of space between the loudest peak in your audio and 0 dBFS (maximum digital level). Leaving headroom prevents clipping and gives mastering engineers room to work.
A filter that allows high frequencies to pass through while attenuating low frequencies below a set cutoff point. Used to remove rumble, mud, or unwanted bass.
The delay between an input signal and its output through a digital audio system. High latency makes real-time monitoring and playing difficult. Measured in milliseconds.
Stacking multiple sounds together to create a fuller, more complex sound. Common with drums, bass, and synth leads to add depth and character.
An extreme form of compression with a very high ratio that prevents audio from exceeding a set ceiling. Essential for mastering and preventing clipping.
Learn more: Mastering BasicsA filter that allows low frequencies to pass through while attenuating high frequencies above a set cutoff point. Creates darker, warmer tones and is fundamental to synthesis.
Loudness Units Full Scale - a standardized measurement of perceived loudness. Streaming platforms use LUFS targets (typically -14 to -16 LUFS) to normalize playback levels.
The final step in music production where a finished mix is polished, balanced, and prepared for distribution. Involves EQ, compression, limiting, and ensuring consistent levels.
Learn more: Mastering BasicsMusical Instrument Digital Interface - a protocol for communicating musical performance data between devices. MIDI transmits note, velocity, and controller information, not audio.
The process of balancing, processing, and combining individual tracks to create a cohesive final stereo or multi-channel audio file. Involves volume, panning, EQ, compression, and effects.
Learn more: Mixing FundamentalsA compressor that splits audio into multiple frequency bands and compresses each independently. Allows precise dynamic control without affecting the entire frequency spectrum.
A process that raises or lowers the overall volume of audio so that the loudest peak reaches a specified level (typically -0.1 dB or -1 dB).
The sound-generating component of a synthesizer that produces waveforms at specific frequencies. Most synths have multiple oscillators that can be blended.
Recording new audio over existing tracks without erasing them. Fundamental to building multi-layered productions.
Positioning audio in the stereo field from left to right. Creates width, separation, and space in a mix by placing different elements at different stereo positions.
An EQ that allows precise control over frequency, gain, and bandwidth (Q) for each band. The most versatile and common type of EQ in modern production.
Learn more: EQ FundamentalsThe position of a waveform in its cycle. When two identical signals are out of phase, they can cancel each other out (phase cancellation), causing a hollow or thin sound.
A modulation effect that creates a sweeping, whooshing sound by filtering the audio with a series of peaks and troughs that move through the frequency spectrum.
Software that adds functionality to a DAW, including instruments (VST, AU), effects processors, and utility tools. Plugins expand production capabilities beyond stock DAW features.
A sliding pitch effect between notes, also called glide. Common in lead synths and bass sounds to create smooth, vocal-like transitions.
Aligning recorded MIDI notes or audio to a rhythmic grid to correct timing. Can be applied at various strengths from subtle to robotic perfection.
A compressor parameter that determines how much the volume is reduced once it exceeds the threshold. A 4:1 ratio means for every 4 dB over threshold, output increases by only 1 dB.
A professionally mixed and mastered song in a similar style used as a comparison point during mixing and mastering to guide tonal and dynamic decisions.
A filter parameter that emphasizes frequencies at or near the cutoff point, creating a pronounced peak. High resonance produces characteristic "squelchy" filter sweeps.
An effect that simulates acoustic space by creating reflections of sound. Adds depth, dimension, and realism to dry recordings. Types include room, hall, plate, and spring.
Learn more: Reverb & Delay GuideA recorded piece of audio used in music production. Can be a drum hit, melody, vocal phrase, or any sound. Also refers to the individual data points in digital audio.
The number of times per second that audio is measured when converting from analog to digital. Standard rates are 44.1 kHz (CD quality) and 48 kHz (video standard).
Harmonic distortion that adds warmth, character, and perceived loudness to audio. Emulates the pleasing distortion of analog equipment like tape machines and tube preamps.
A technique where one audio signal controls the processing of another. Most commonly used for sidechain compression, where a kick drum triggers a compressor on the bass for rhythmic pumping.
Learn more: Sidechain Compression TutorialThe order in which audio passes through different processors and effects. The sequence matters - EQ before compression sounds different than compression before EQ.
A visual tool that displays the frequency content of audio in real-time. Essential for identifying problem frequencies and making informed EQ decisions.
