From the software point of view, digital audio workstation can be divided into the following modules: operating platform, audio processing interface, file format, third-party software and other related software.
Hardware:
Professional sound card: collect pure sound
Computer workstation: used to calculate and edit sound signals.
DSP Acceleration Card: Decompose the calculation of sound from the CPU of the computer, reduce the pressure on the computer, and provide you with more professional sound effects (often the hardware algorithm is better than the software algorithm).
Burner or tape drive: If you want to make a CD or tape.
Software:
Editing software: cutting and splicing audio.
Processing software: processing audio, such as equalization, delay, dynamics, etc.
Post-downmix software: polish the stereo audio track synthesized by multi-track data in the previous step.
The most important equipment factors affecting sound quality are hardware distortion and signal-to-noise ratio, as well as the advanced degree of acoustic and mathematical algorithms used in each processing cycle.
