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.

WebBasically you are trying to cast an array of four 8-bit values which can have any alignment they like (byte alignment) to a 32-bit float value which needs 4-byte alignment. And the two just don't mesh. Instead you need to work the other way around - cast a type that has smaller alignment requirements over the type that has larger requirements. indian skies rv park coolidge az ratesWebThe BitConverter class helps manipulate value types in their fundamental form, as a series of bytes.
