CountingPrint Class Reference

Minimal Print wrapper that counts the bytes actually written to the wrapped output. Used by WAVEncoder to track the number of encoded bytes an external AudioEncoderExt has emitted, since AudioEncoder::write() reports the number of raw PCM input bytes it accepted, not the number of encoded bytes it produced (these differ for compressing formats like ADPCM).
