How do you extract Stereo (Left and Right) signal from the FFT #878
-
Hello!I receives Audio signal from the BluetoothA2DPSink and then I wants to extract Left and Right signal from the FFT. Haven't found any examples of this so I hope this is possible an there is a simple solution?. Thank you so much! |
Beta Was this translation helpful? Give feedback.

FFT is a very expensive operation (both using a lot of memory and doing a lot of floating point operations), I will never do it on a stereo signal and if you feed it with stereo, it is converted to a mono signal first. |

If you really want do do this you will need to split up the signal yourself and you will need to set up 2 FFTs.
