Audio storage guides with exact boundaries
Three guides explain PCM payload, decimal and binary units, and why compressed output needs different evidence.
GB versus GiB for audio recording storage
Read card labels and operating-system displays without treating decimal and binary storage units as interchangeable.
Read guideWhy FLAC and MP3 size is not exact from PCM settings
