Our Delay and Reverb Calculator is a specialized tool developed to assist audio engineers, music producers, and sound designers in accurately calculating the parameters for delay and reverb effects.
These calculations are essential for achieving desired sonic characteristics in various audio applications, such as music production, live sound reinforcement, and post-production for film and video.
Delay and Reverb Calculator
Calculate delay times and suggested reverb settings based on the tempo of a song.
Let’s say you want to create a slapback echo effect, where the delayed signal arrives 30 meters away from the source.
We can calculate the delay time using the formula:
Delay Time (ms) = Distance (m) / Speed of Sound (m/s) × 1000
Delay Time (ms) = 30 m / 343 m/s × 1000
Delay Time (ms) = 87.45 ms
To create a slapback echo effect with a delay of 30 meters, you would need to set the delay time to approximately 87.45 milliseconds.
Reverb Calculation
Suppose you want to calculate the reverberation time for a small recording studio with dimensions of 5 meters x 4 meters x 3 meters, and a total absorption area of 50 square meters. We can use the Sabine equation:
Room Volume = 5 m × 4 m × 3 m = 60 m³
Reverb Time (s) = 0.163 × Volume (m³) / (Total Absorption Area)
Reverb Time (s) = 0.163 × 60 m³ / 50 m²
Reverb Time (s) = 0.196 s (or approximately 196 milliseconds)
The calculated reverberation time for this small recording studio would be approximately 196 milliseconds.
Delay and Reverb Calculation Formula
The calculation formulas used in a Delay and Reverb Calculator app are based on fundamental principles of acoustics and signal processing.
For delay, the key formula involves the relationship between the delay time (typically expressed in milliseconds) and the distance the sound travels (in meters or feet).
This calculation takes into account the speed of sound, which is approximately 343 meters per second (or 1,126 feet per second) at room temperature.
The formula for calculating delay time is:
Delay Time (ms) = Distance (m) / Speed of Sound (m/s) × 1000
For reverb, the calculations are more complex, involving factors such as room dimensions, absorption coefficients of materials, and the desired reverberation time.
The widely used Sabine and Eyring equations are commonly employed to estimate reverberation times based on room volume and surface areas.
Reverb Time (s) = 0.163 × Volume (m³) / (Total Absorption Area)
What is Delay and Reverb?
Delay is an audio effect that creates copies of the original sound, introducing a short time gap between the original and the repeated signals.
This effect can be used to create echoes, doubling, and other creative sonic textures.
Delays can range from short slapback echoes to longer, more pronounced repeats.
Reverb, on the other hand, simulates the natural acoustic reflections that occur when sound waves bounce off surfaces in an enclosed space, such as a room or a concert hall.
Reverb adds depth, warmth, and a sense of space to audio recordings, making them sound more natural and realistic.
Benefits of using Delay and Reverb Calculator?
