The book contains many technical terms and radio mastering best practice terminology. As a result, it could be difficult for newbies and amateurs for understanding the professional music mastering process for broadcasting. The purpose of writing this article is to present radio mastering process into a simpler way so that anyone can get the glance of Mixing and Mastering Services for radio broadcasting. The writing will be published in two parts which will reveal what happens to your song when it plays on radio and what actually happens on a radio broadcast (Understanding the Chain Process). So let us move forward to the first part of our writing.

What Happens to Your Song when it Plays on Radio?

Many of us, who belongs from the professional mixing and mastering industry, know how to process a crude piece of recording before it plays in the FM airwaves. My purpose of writing this blog is to remove all the myths and misapprehension regarding the secret art of radio mastering. Most of the radio stations worldwide use an audio transmission process from station’s transmitter. The main function of the processor is controlling the transmitter’s peak modulation. This peak modulation’s frequency should match the standard regulatory body of the nation where the radio station is situated.

Just, like the other way round, there are only a few radio stations use limited functional peak. In reality, most of the radio stations use a complex chain of an audio. Using this technique, allow the broadcast station to play music louder within the maximum peak level. This maximum peak level is different for radio broadcasting in different countries. For example, the VU meters used in Australia and USA is recommended by EBU for radio broadcast in different countries in Europe. The IEC recommendations are as follows:

Analogue Peak Programme Meter: IEC 268-10
Digital Peak Programme Meter: IEC 268-18

Cancelling Noise and Increasing Loudness: Best Online Mastering Service provider and designer of the broadcast have achieved the knowledge of getting the maximum loudness that also consist audio punch and cleanliness. The mantra behind this success is very simple. Broadcasting an audio clip via radio depends on the quality of the source. So the bottom line is the relation between the quality of the broadcasted audio and the source audio is directly proportional.

The Competition of Being Loud – Radio Signal vs. CD: Singers, composers, and producers wanted to get the loud production of music. And on the other hand radio stations wished to offer the loudest signal. This war stayed for around 25 years. Before this competition started, radio stations were used to make simple audio clips louder. Mixing and mastering services providers for radio broadcasting has learned this technique for over 25 years. But now the technique has drifted to the CD Mastering Services industry.

Radio Broadcasting

Problem Today with Radio Broadcasting: The biggest problem with radio industry is facing today is that powerful and sophisticated sound processing for radio broadcasting transmission is no longer coexist today. Perhaps a professional who offers audio mastering services online can help you to deal with this. If someone limits the multiband compression of the source digitally that also reduces the peak of the short term to average ratio. As a result, the processor of the broadcast station handles the mastering material less naturally and less gracefully than it handled the source stuff.

Broadcast Process Affects Hyper-Compressed Material – Fact or Myth: The process of broadcast affects the hyper-compressed stuff. This is true only if there is no dynamic long-term range is coming in. In that case, broadcasting processor’s AGC will no longer be able to reduce it any further. However, a typical processor will still operate the hyper-compressed stuff and it will reduce its peak to the average ratio.

Not to mention it additionally, a hyper-compressed stuff does not sound loud when it plays on air. It sounds like the music is broken or distorted and flat. So your listener does not enjoy the music much. As a result, they pay no attention what is playing, or even worst they turn off the radio.

What Happens when Hyper Compression Combines with Major Market Broadcast Processing Level: When Hyper Compression get combined with broadcast processing, it exclude the drama, feel and life from the music. In extreme cases, the sound is completely distorted. The mastering sound seems flat, small and busy.

The quality of the Receiver’s Output Also Plays a Big Role: Even if you have done all the radio mastering process correctly and followed all the tips revealed here, you cannot be sure how your mastered audio will perform at the output speaker. The reason behind this many car users use a cheap quality of car speaker that can affect the quality of your audio mixing. On the other hand, economical ear buds and boom box can also be responsible for a poor output. So maybe your music is really sounds great but that does not mean that it will perform well on the output device. Errors in transmitting process and techniques can also play a vital a role in order to diminish the quality of your song. Well, that is none of your lookouts. You just focus on your part of the job and let the rest to happen the best.
