Polarity buttons (sometimes called phase buttons) are common on audio interfaces to keep stereo inputs in phase with each other. Basically, the peaks are where the troughs once were, and vice versa. When you “flip the polarity” of a waveform, it turns the waveform upside down.
Polarity – The “direction” of a waveform. Common examples are words with p’s, b’s, t’s, k’s, and d’s. Plosives – Sounds made from the mouth that blow quick bursts of air. Most audio interfaces have a button that sends this power to a microphone that needs it.
The power necessary to get a condenser mic to work. Omnidirectional (or Omni) – A microphone that picks up sound from all direction. A sound that has one source, rather than two. Layering – Recording several copies of one musical part to be performed on top of each other. The input (the instrument) is delayed so that the output (the recording) is several milliseconds behind, causing an frustrating delay in a performer’s headphones. Latency usually refers to the delay that occurs when someone tries to record something when there are too many plugins on the session. Latency – The amount of delay between between the input and the output of a signal. If it’s peaking at -1dB, it has 1 dB of headroom. For example, if a sound is peaking at -5dB, it has 5dB’s of headroom. The louder the sound, the less headroom it has. Headroom – The amount of volume a channel can take before distorting. Known for handling more aggressive or loud instruments. Known for being very accurate.ĭoubling – Recording a part multiple times to get a “thicker” sound.ĭynamic mic – A microphone found in both studio and live settings with a limited frequency range and lower sensitivity. In general, you want to give a channel enough headroom so that clipping doesn’t occur.Ĭondenser mic – A microphone commonly found in studios with a large frequency range and high sensitivity. “Clipping” is usually used when a channel on a DAW or mixing board has too much volume being sent into it. For example, sound mixers have multiple input channels and output channels.Ĭlipping (or Peaking) – Another word for distorting. In other words, a microphone that picks up sounds in front of it, but not behind it.Ĭhannel – Similar to a bus, a pathway through an audio device. This setting can be found in your DAW’s preferences.Ĭardioid (or Unidirectional) – A unidirectional microphone with a heart-shaped pickup pattern. The rule of thumb is to set your buffer size as low as possible when recording and as high as possible when mixing.
Higher buffer sizes have greater latency, but are less susceptible to crashing. Lower buffer sizes have lower latency, but are more susceptible to crashing. For instance, running a recording session at 24bits means the audio will be more accurate than if it was running at 16bits.īuffer size – How much data a computer program can handle at a time. The higher the bit depth, the more accurate the output. Bi-Directional – A microphone that picks up sound from the front and back, but not the sides.īit depth – A measure of the accuracy of a program.
