A home studio generally has only a few microphones, no console, and a basic audio interface like an Mbox (for Pro Tools), or an Apogee Duet (for Logic). Once we’ve processed the data within the DAW, we convert the signal back to analog (D/A), send it back to the console faders (not the pre amps), and from there the signal is sent to the power amps, which power the speakers.Ī home studio deals with less complexity in comparison to a professional studio. In order for the DAW (Digital Audio Workstation) to read and process the information. The pre amps are used to change the impedance and amplify the signal to line level – the optimal operation level for most professional gear.įrom the console pre amps, the signal flows to the Analog to Digital Audio Interface (A/D), which converts the analog signal to a digital signal. Once the audio signal is converted into an electric signal, the electric signal is sent to the console pre amps. Within our diagram, the microphone(s) take the sound waves from the sound source and convert the sound waves into an electric current (through the process of transduction). Transduction is the process of converting one type of energy into another form of energy. Signal flow begins at the sound source, with a transduction stage. Yet if (and when) problems do arise between your source(s) and output (recording medium), a strong understanding of signal flow will help expedite the trouble shooting process, saving you and your musicians valuable time in a service-based industry where issues of money, and creativity play a critical role in the outcome of the session.
Understanding and planning out the signal flow for a recording session will help in keeping a session stress-free and focused on the music. Signal flow is one of the most essential concepts to the success of the recording experience.
