Digital Audio Formats explores the world of digital audio, revealing how encoding technologies have transformed music and listening. The book navigates the complexities of lossless and lossy codecs like FLAC, AAC, MP3, and OGG Vorbis. It examines the trade-offs between audio quality and file size, showing how psychoacoustic models are used to compress audio while retaining perceived quality. One intriguing fact is how early digital audio recording influenced today’s streaming era. Another is how social and economic factors affect which audio formats become popular. The book begins with digital audio fundamentals before diving into specific codecs. It contrasts lossless compression techniques, like those used in FLAC, with lossy methods in AAC and MP3. Objective quality metrics, such as PEAQ, are explored. The book uniquely combines technical analysis with practical considerations, providing a balanced view of each format's strengths and weaknesses. It concludes with real-world applications, from music streaming to archival storage, highlighting the absence of a one-size-fits-all codec.
