WebFeb 27, 2024 · - A float is 4 bytes, you could shave off 2 bytes and save half of the bandwidth if you use Int16 instead because that is only 2 bytes. Audio using floats sits in the range -1.0 to 1.0. Using Int16 means your values should be in the range -32768 to 32767. Before sending the data you convert it to Int16, and then back to bytes and send it. WebJan 3, 2006 · The only gotcha is that the byte ordering of your float may be opposite of how the BinaryReader/Writer handles it (mantissa first instead of sign/exponent first). But even if you have to use 4 individual BinaryReader.Writes to write the bytes in the right order, performance should still be OK.
