Hi,
is it possible to send some audio signals e.g. .wav from one port to an other port over LV? Now I send only stings (numbers and text). I like to test a signal, I will sent it from one port to an other port and after this I will compare both signals with a graph, but I don't know if I can sent .wav, too. --------------------

If you use SI Read.vi (Sound Input) you will get sound arrays: 1D [I8] for mono 8-bit sound 1D [I16] for mono 16-bit sound 2D [I8] for mono 8-bit sound 2D [I16] for mono 16-bit sound depend what configuration (SI Cinfig.vi) you use. There is few method to send it as string: 1. from String subpalete: Array to Spreadsheet String or 2. from Advanced>>Data Manipulation subpalett : function TypeCast : - to input connect sound array from SI Read.vi - to type connect empty string output will be string When you recieve string from serialport you sholul use just this method like when you send audio to serial.so regards Mikrobi
