You Speak – We Type

The general issues occurring in a poor audio recording are:

  • The microphones placed away from the speaker. In this case, there are high chances of audio recorded as faint voices.
  • Over speaking that occurs when people talk over the top of one another. This drives away the clarity from the main source involving multiple voices without focus.
  • Background noise drowning out the speakers, we mean the disturbances that affect the clarity and takes the conversation to control diverting the listener to many other sounds other than the topic focused on.
  • Let us analyze the issues in detail,

    Less background noise:

    While recording the audio, it is advisable to get more of the sound you need to hear the most or the sound relevant to the subject and less of the irrelevant sounds like (wind sounds, camera hiss, fans, air-conditioners etc..) commonly said to be the “noise”. We understand that it is tough to get rid of the background noises totally, but minimizing back ground noise to the maximum can input more to the quality of the audio content recorded.

    Record in a manageable environment:

    It is better if the audio recording is done in a closed sound-proofed building. Else you can have the recording process indoors with the windows closed and air-conditioners switched off. If in case the recording is surely to be done in outdoors, you can try to spot out a quiet location as well.

    Always record close to the main sound source: 

    The audio recording equipment is to be kept close to the main sound source whether it is recorded indoors or outdoors. Even if the camera needs to be moved away from the source, a microphone can be positioned closer to the source.

    Sound: noise ratio

    To get a high sound to noise ratio, the audio should be recorded at the highest level possible, but not high to the level of getting distorted. Recording the audio level too high can also result in warp or deformation of the audio. To obtain a better signal to noise ratio, the camera is to be fixed closer to the sound source and should be recorded in a handy environment.

    Let’s say you are involved in the process of creating a TV show and the audio and video recording has been done. But during the editing and composting processes, if you come to know that the mixed audio level of the speech and the music added later is too high, you can always reduce the audio level of both the source of sound (music and speed) and along with this, as a windfall even the unwanted and irrelevant sounds like camera hiss etc are also reduced simultaneously. But on the other hand, if you come to know if the mixed audio level is too low, when you try to make it louder, even the unwanted sounds get louder as well. Always recording your audio to the highest without getting distorted will add up to the quality of the audio material.

    Checking Audio input levels:

    If your camcorder allows you with a visual display of the audio input levels, you can then fix the audio level to be close to zero but not zero definitely. But the most disadvantageous thing is that many camcorders in the market do not have options with visual display of audio levels, hence manual alteration of audio levels becomes impossible. In such cases we need to hear out for distortion. In the case of digital audio recording like CDs, zero is meant to be the point at which the signal shears or warps.

    Projecting the speaker’s voice: 

    It is advisable to record a speaker’s voice that comes from the chest in support with the diaphragm. This type of chest voice is intended more towards the microphone, rather than that of the voice from the throat.

    Clear and precise speech: 

    Ask your speaker/speakers to speak clearly, slowly and of course with proper pronunciations’, especially when technical terms and unique names are dealt with. In the case of group discussions or meetings, it is advisable to place the microphone at an equal distance from everyone who is likely to offer a speech. This can result in a high quality transcript.

    Separate recording of exceptional audio events:

    Sometimes while recording you might need some specific audio events to be recorded separately. This is done to emphasis the importance of such specific audio events in the audio. This can be recorded separately and included into the audio during the editing process.

    Say you record a radio show and it is a group talk program. At certain places you might have speakers expressing their applause through clapping. You might want the claps to sound louder, but increasing the combined audio level can disrupt the dialogue levels. In such situations you can re-record the necessary audio events like clap sounds separately and include in the final audio.
