用法筆記

Almost always attributive (lossless format, lossless codec, lossless compression) or predicative after a copula. Subject is usually a technical noun: file format, codec, compression method, or energy transfer. Often paired in contrast with 'lossy', which is the everyday opposite term in audio and image work.
