BASF 8100 CrO2 is a type of high-fidelity audio tape formulated with chromium dioxide particles, designated for high-performance sound recording. The tape is designed to offer an extended frequency response and low noise levels, making it suitable for professional audio applications. The CrO2 formulation contributes to improved dynamic range and a more detailed sound reproduction compared to traditional oxide tapes. Specifications typically include a thickness of around 1.5 mils and a sensitivity rating often equivalent to +3 dB over standard ferric tapes. The BASF 8100 is particularly favored by audiophiles and professionals for its capability to preserve audio quality over time. Practical applications include use in studio recordings, archiving, and audio mastering, allowing for high-quality stem mixes to be captured on magnetic medium.
