Acoustic Music Production – Part II – Recording acoustic live sessions

Some musicians prefer to record themselves with other musicians in the same room. With this, some technical difficulties in recording each signal may appear. For example, we don’t want the sound of the drummer appearing in the microphone of the lead singer. To avoid this undesired interference, the choice of the microphones is, again and always, essential.

Microphones can be classified according to their pattern and according to their transducer type.

The pattern indicates from where in the space the microphone can recognize the signal. The figure below shows the most common type of polar patterns:



The figure below shows the microphones according to their transducer:



The condenser microphone is more sensitive to the variations in the sound pressure and, due to this, it can capture a more detailed signal. However, on stage this can be a problem, since the noise from the audience, for example, can appear too much in the recording. In the case of recording in studios, the dynamic microfone is more indicated to record both instruments and voices.

The combo of dynamic + cardioid is the most used pattern for recording voices at live sessions (studio or stage) because this pattern has good rejection from the things that are not in front of the microphone. So, in the video below, we chose to record the voice with the classic Shure SM58. The guitar had the mid-side technique on it (which was talked about in the previous post) and a direct injection as well. Enjoy!
