| struct | AppropriateSumType< T > |
| | We reduce the number of samples in a datastream by summing (binning) or averaging. This will result in the same number of channels but binSize times less samples. If Average is true the sum is divided by binSize. More...

| class | ChannelAvg |
| | We average pairs of channels in a datastream. E.g. if we have 4 channels we end up with 2 channels. The channels will be (channel_1 + channel_2)/2 (channel_3 - channel_4)/2. This is equivalent of stereo to mono conversion but will also work for quadric, sexic or octic audio. This will not work if you provide single channel data! More...

| class | ChannelAvgT< T, AvgT > |
| | We average pairs of channels in a datastream. E.g. if we have 4 channels we end up with 2 channels. The channels will be (channel_1 + channel_2)/2 (channel_3 - channel_4)/2. This is equivalent of stereo to mono conversion but will also work for quadric, sexic or octic audio. This will not work if you provide single channel data! More...

|
| |
| struct | ChannelBinDiff::ChannelBinDiffState |
| |
| struct | ChannelBinDiff::ChannelBinDiffStateT< T > |
| |
| class | ChannelBinDiffT< T > |
| | We first bin the channels then we calculate the difference between pairs of channels in a datastream. E.g. For binning, if we bin 4 samples in each channel we will have 4 times less samples per channel E.g. For subtracting if we have 4 channels we end up with 2 channels. The channels will be channel_1 - channel_2 channel_3 - channel_4 This is the same as combining binning and subtracting channels. This will not work if you provide single channel data! More...

| class | ChannelDiff |

| class | ChannelDiffT< T > |
| | We calculate the difference between pairs of channels in a datastream. E.g. if we have 4 channels we end up with 2 channels. The channels will be channel_1 - channel_2 channel_3 - channel_4 This is similar to background subtraction between two channels but will also work for quadric, sexic or octic audio. This will not work if you provide single channel data! More...

| class | ChannelReducer |
| | We combine a datastream which consists of multiple channels into less channels. E.g. 2 to 1 The last target channel will contain the combined values of the exceeding source channels. More...
