So, as I am working on my senior capstone project, I thought I would share it, as it seems an interesting and relevant topic to discuss. So, what am I doing? I am working in part on a study to tell the just noticeable difference (JND) in reverberation time. There have been very few studies on this in the past, only one notable one that has set the accepted number, of a 5% change to reverberation time. Initial impressions say it might be greater than that. How are we doing this? Well, the best way would be to take a recording in a space, and change the space to change the reverberation time, and take another recording, and compare. This would be very impractical to do in real life though. But, luckily, we have the power of computers now. Odeon is a room acoustics software that can accurate do a lot of things. The room used is the Philadelphia Academy of music. This space sounded most natural in Odeon. This space had already been modeled previously, with all materials assigned, so I did not have to worry about that. Odeon has anechoic recordings available, essential for modeling and convolving this correctly. First, an entire anechoic recording was placed on the stage, but it didn't sound natural due to a few things, including no stereo imaging, and directivity of each instrument not taken into account. So I took each individual instruments anechoic recordings, and placed them in their respective positions on stage. I aimed all instruments at the conductor (let me know if you think this was the wrong thing to do), and put the listener in a central position in the audience, facing the stage. If you want to know what instrument is what: (speaker on stage is conductor) And first person view of stage from listener: Then, ran the convolutions in odeon to get an output file. This is what it sounds like. https://hartford0-my.sharepoint.com...1AkvPC8gty_n4Bh2yIENi7tSfKzyvDumpl-Q?e=F7AuCm Here is the original anechoic recording https://hartford0-my.sharepoint.com...JGhGsMevMk0asBetYCo5gPDzpeDtQQB_vmRA?e=9fDhHC What next? Right now there is a reverberation time of 1.48 seconds. more convolutions need to be made to compare. First, i want to get the base recording as realistic as possible. Thoughts on How realistic the convolved recording is, and what may be unrealistic about it?
