Advertisements broadcasting service on radio is required to report data after performing broadcast correctly and should be accountable to the owners of ads on the date, hours of broadcasting and the number of ads that aired under the contract. But in practice, it is possible that the amount of advertising broadcast time and ads are not in accordance with the contract. Therefore, it is necessary to do the monitoring. Monitoring and recording of advertisements broadcasted on radio is very important activity, with the aim that the owners of the ads can monitor their ads in accordance with the contract, so that the organizers of the radio broadcasting rights can be paid. Monitoring and recording the aired ads audio is done by marking the identity of owner. Research on owner�s identity is done by insertion of custom DTMF code method via mixing process (mixing) as a marker on the transmitter side and read back on receiver side for the benefit of tagging the audio ads content. Insertion of the code through the mixing is done using the principle of steganography. In particular, this insertion technique is done in time domain. This study was conducted with a variety of ads audio, and then analyzed regarding the placement of custom DTMF code, break time influence on the quality of readability of the code in the receiver, the influence of noise (Brown, Pink and White) on the readability of the code. The results showed an audio signal and the inserted custom DTMF codes can be read properly and wasn�t modulated with audio or noise, so it does not interfere with readability of the code and the aired ads audio quality.
