So if the recording volume level increased by 8dB, then you would only hear a 2dB volume increase. If, for example, you wanted the volume levels of a recording to only increase by at most 1/4 of the amount they would normally increase, then this would correspond to a Ratio of 4:1. The "Ratio" setting limits the amount the volume level of the recording increases at any one time. It then gradually attenuates the sound to bring it down below the dB level, and does it in such a way that the listener will not be aware the attenuation is occurring. The "Threshold" setting works by detecting when the sound recording volume exceeds a defined decibel level. The "Release Time" setting is the time (between milliseconds) that it will take to remove the gain adjustment once gain adjustment is no longer needed. The total gain adjustment required will be gradually introduced over this period. The "Attack Time" setting is the time (between milliseconds) that it will take to apply the gain adjustment. e.g., A CD can handle a much greater range than a cassette tape. It also has a use for recording audio from one medium to another, where the two mediums are not capable of handling the same range of volume levels.

CompressorĪ Dynamic Range Compressor limits the volume levels of a sound recording so that it stays within a certain loudness range.Īn example of where it is used is in TV broadcasting, where it ensures that the volume levels of ads are perceived as being louder than the television program itself (without any change in the actual broadcast volume). You also specify the level where it kicks in dB (default -8db). Distortion is measured between 0.0 (off) and 1.0 (clipping). For instance, it is popular for use with guitars. While normally we do everything to reduce distortion, sometimes you want to add it. Note: Chorus is a very useful way to make a mono source sound more stereo. The chorus sound effect is used to make one voice or one instrument sound like 3 voices or instruments by playing the original with variably delayed and slightly pitch changed copies of the original. It is very usual to use a high-pass filter of about 300Hz on all voice recordings to improve intelligibility. This is useful if you want to make your recording sound 'clearer' or less 'muddy'. High PassĪ high-pass filter (sometimes called a low cut filter) removes all low frequencies below a specified Hz. Low PassĪ low-pass filter (sometimes called a high cut filter) keeps frequencies in the audio below a certain value. More reverb is called wet, no reverb is called dry. It usually occurs when someone is speaking in a room, hall, etc. Reverb is many small reflections of the sound that come after a set time. This does the same job as the normal pitch shifter except it keeps the vocal formants in tact creating a more realistic result. This changes the pitch of the audio without changing the speed. It sounds a bit like the person speaking is in a large stadium or is shouting between two mountains. EchoĪn echo is a repeat of the sound after a short time (usually 1 - 4000ms). An 3-Band Equalizer is a special equalizer which can change volume level at band 100Hz, 900Hz and 2500Hz.
