WebThe arithmetic right-shift ( >>) will do the filling for us automatically if the sign bit is set, so I usually do it this way: int bitsToExtend = Long.SIZE - bitsPerSample; float sample = (temp << bitsToExtend) >> bitsToExtend. (Where Long.SIZE is 64. If our temp variable wasn't a long, we'd use something else. WebHow is audio data stored in binary? A microphone converts sound waves into voltage changes. If a microphone is plugged into a sound card then the voltage can be sampled at regular intervals (the sample rate) and each value converted into a binary number. The sound card can recreate the stored sound using a Digital to Analogue Convertor (DAC).
