AMROC is a room mode calculator that is not only displaying modes in a table, but also shows interactive diagrams to help you understand their distribution over frequency in an intuitive way.(...) Why could one be interested in computing this room modes? Even though those eigenmodes exist in every room, its possible to reduce their negative effect on the musical enjoyment. Our intent is to achieve a mode distribution that is as equal as possible. Amroc shows the tune (musical notes) of every mode. You will see, that - especially at the lowest modes - notes without any mode will be followed by notes with multiple modes. This leads to different reverberation times for different notes and is perceived as different loundness of those notes. A better mode distribution means less room-induced differences between notes. The locations of modes are primarily depending on the dimensions of the room, and so its most effective if you are in the lucky position to plan a room as a whole. Its not right, that you can eliminate the problem of droning bass frequencies by splaying your walls. It will reduce the effect of the axial modes by moving this resonant frequency range but its not sure, that the distribution of the modes will be better with one or some walls splayed. However, it will be much more difficult to compute them in advance.
