This module covers the theory and practicalities of sound and music recording. This will start with an introduction to the fundamentals of sound, and build to an understanding of room acoustics. This theory will be supported by a series of practical sessions devoted to the handling and analysis of audio signals. The module will also introduce the art and science of recording audio, covering the technical and creative aspects of recording and producing music from microphone to master. The module’s sessions will therefore include lab-based sessions covering key software skills, and studio-based practical support.

There are 2 assessments for this module, which will be issued towards the start of the teaching sessions.
Studio Recording Exercise: Students will produce a multitrack musical recording using a variety of microphone and mixing techniques. The mix will incorporate at least one element recorded using a stereo microphone pair of a type covered on the course. Students will be required to deliver their finished mix, as well as isolated stems from the stereo pair. An accompanying report will describe their stereo recording work, how this was incorporated into their mix, and any additional recording, mixing or mastering work performed on their mix.
Acoustic Analysis Exercise: Students will create an example of auralisation by making use of an anechoic recording of a musical instrument and an acoustic impulse response. The student should record the anechoic material themselves and make use of an acoustic impulse response from OpenAIR (although they will be provided with the tools required for acoustic impulse response measurement). The students will conduct an analysis of the musical recording, the impulse response, and the auralisation result and will relate these analyses to the acoustic properties of the chosen musical instrument and the acoustic features of the impulse response measurement space. The results will be presented in a technical report (making suitable use of time- and frequency-domain analysis), submitted along with the audio files and MATLAB analysis code

Formative Feedback
Regular labs will allow students to engage with the module material and receive help with, and feedback on, their practical work.
Emails to the Module Staff with Questions / Comments will be answered as soon as possible.
The studio drop-in sessions will allow students to receive further support for their work on the recording studio exercise.
Summative Feedback
For each summative assessment students will receive a customised feedback sheet, showing the mark breakdown in each of the key areas being assessed along with personalised feedback and suggestions for improvement. The comments explain how well you have met the learning objectives, and also give you feedback about the things you could improve in future assignments).
