Correct recording format
You need to decide in advance which recording format you want to use. If you use 8bit and 8000kHz for recording, don't expect to get good results. The best format for recording is wav or aiff. Use settings of 44100khz and 16bit to obtain the best quality (this is the minimum setting for obtaining good quality, you can set higher values).
We always recommend not using MP3 format for recording, as this format cannot capture the entire original audio spectrum. However, if you have to use MP3 format for recording, use a setting of no less than 320kpbs.
Placement of wheat
In order to capture the complete acoustic range of audio, the distance between the microphone and the mouth should be appropriate during recording. Our experience starts with 9 inches. If it's too close, you may record breathing sounds or something. If it's too far away, the recorded sound sounds dull and weak. At the same time, you need to use a blowout preventer to filter out breathing sounds and explosive sounds such as "b" and "p". These explosive sounds are difficult to solve through post-processing.
Pay attention to the level
Ensure that your recording level is within the green range! This is very important because once your audio starts to be clipped (the signal level exceeds 0 db, which means it turns red), your recording will have a troublesome distortion that cannot be processed later on. However, the level should not be too low as it will cause more noise in the signal. A suitable level of -6db to -4db is a good starting point. Pay close attention to the recording level throughout the entire recording process.
Don't think about relying on post processing to solve it
Don't drag errors to the mix and master stage to remove them. In the later stages of post production, audio can be modified, but the result of the modification still depends on the quality of the original audio. Good recording=good mixing, and vice versa.
