Comparison Protocol


Title

The main title of your article must be as short as possible and must reflect the comparison aims.


1) Comparison Aims

Describe your intentions and explain why your records could be interesting.


2) Source Description

(photos are welcomed [500 Ko Max])

Give precise details about the sound source and the performance.

For instance

  • Singer/Speech: Female or Male
  • Instruments: Brand, Model, Amplified or not, Configuration (e.g. which electric guitar microphone operates)
  • Amplifier: Brand, Model, Knobs Positions.
  • Percussive Instruments: Brand, Model, Measurements, Tuning.

3) Room Description

(photos are welcomed [500 Ko Max])

Indicate the room/place dimensions and specify if there are some acoustic treatments. 


4) Microphones

List all the engaged microphones and add technical informations such as:

  • Brand
  • Model
  • Type (Dynamic, Condenser, Ribbon, Electret, etc.)
  • Directivity

For instance:

  • Microphone 1: Shure, SM57, Dynamic, Cardioid.
  • Microhopne 2: AKG, C414 XLS, Condenser, Cardioid.

Comment: Keep your arbitrary microphones order for the following sections.


5) Positioning

(photos are welcomed [500 Ko Max])

Depending on your comparison aims, explain how did you place the different microphones around the source and add positioning informations such as:

  • Distance (cm and/or inches)
  • Slope (xx°) where 0° is equivalent to the ground plane. 

For instance:

  • Microphone 1: 2 inches (5.08 cm), 90°.

6) Engaged Preamplifier and Converters

(photos are welcomed [500 Ko Max])

Mention all devices that have conveyed the signals from the microphones to your final digital samples. Don’t forget to add precise informations such as: 

  • Device (Console, Recorder, Audio interface, Any Audio Rack)
  • Brand
  • Model
  • Type (e.g for recorders: Digital, Tape)

7) Gain/Trims

Let us know an approximate (for analog) or precise (for digital) gain/trim percentage you adjusted for each microphones.

Comment: This section is especially useful for absolute comparisons in order to compare microphones sensitivity and signal-to-noise ratios.


8) Samples

Only AIFF or WAVE formats are allowed (without previous destructive conversions). Those samples can not last more than 20 seconds ! 

Also, the beginning of your audio sample name will be the microphone model. According to your comparison category (Absolute, Distance, Slope or Other), please don’t forget to add essential informations such as distance (cm and/or inches) for distance comparison, slope level (xx°) for slope comparison, etc. 

Comment: Indicate the bpm if there was one.

For instance

Slope Comparison:

  • SM57, 90°
  • SM57, 67,5°
  • SM57, 45°

Distance Comparison:

  • STC2, 1 inch
  • STC2, 2 inches
  • STC2, 4 inches
