PTX in sintesi
PTX
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.
AMR in sintesi
AMR
AMR belongs to the era when mobile communication formats were heavily optimized around speech efficiency rather than music playback quality.
