@Alfred can you explain the difference between convolution reverb and algorithmic reverb with real life examples?

@bmacmixer Convolution reverb is created by sampling real reverberations from a real space, or a synthetic impulse. It takes the characteristics of the sampled space and applies it to audio recordings. An example of this is recording a thunder clap in a tunnel and using the reverberation of that sound to create a realistic sounding digital reverb. Algorithmic reverb is created by programming an algorithm to emulate the sound of a particular space. An example of this is recreated the sound of a cathedral or any other real-world space using parameters like decay time, pre-delay, and dampening.

@Alfred but don’t convolution reverbs have parameters ?

@bmacmixer Yes, convolution reverbs do have parameters. These parameters can be used to adjust the sound of the reverb in order to achieve the desired effect. These parameters include the size and shape of the sampled space, as well as the amount of reverberation (wet/dry mix), dampening, pre-delay, and more.

@Alfred Are algorithms used in convolution reverb parameters?

@bmacmixer Yes, convolution reverb parameters use algorithms which control the processing of the sound waves. These algorithms determine how the sound is processed and ultimately, how it will sound after being processed. The algorithms are used to blend the wet and dry signal to create a more natural sound with a wide range of sonic possibilities.

@Alfred can you show me a small example of a convolution reverb in C++ and JUCE?

@bmacmixer Yes, a convolution reverb in C++ and JUCE can be implemented with the following code snippet: // Code for a convolution reverb using JUCE juce::dsp::Convolution convolution; juce::File pathToImpulse = juce::File(juce::File::getSpecialLocation(juce::File::SpecialLocationType::userApplicationDataDirectory).getChildFile('Sounds/impulse.wav')); convolution.loadImpulseResponse(pathToImpulse, true, true, 0); // Create a mix object to control the wet and dry signals juce::dsp::Mixer mixer;

@Alfred can the impulse file be an ambisonic decoded sound?

@bmacmixer Yes, the impulse file can be an ambisonic decoded sound. However, the decoded sound must be in a supported audio file format such as WAV or AIFF to be used with JUCE's Convolution reverb.
