How do you make your voice clear in a song?

1. Filter out the noise by cutting very low frequencies with an EQ.

2. Use a noise filter like WAVES z-noise ot izotope noise remover (waves is better)

3. use a compressor to compress the sound, usually a ratio of 4:1 will do the job, just trust your ears and listen to a reference, (something you want to sound like)

4. Last but not least - GET A GOOD SINGER!!
