Mono summing is often used as a quality check in different audio industries. It’s used when sound engineers wants to get an appropriate estimation on how the material will behave in different kind of setups such as stores, radio broadcasting. One of the more recent mono devices is the smartphone and there are millions of users allover the world."In 1961 US started to broadcast radio in stereo. The monophonic users were outnumbering the stereophonic users and this quality check was a necessity to make sure that the monophonic listener would be able to get the main message and/or the essence of the material that was broadcasted. One might say the situation reminds a bit of today's millions of smartphones when playing through the phones speaker. The method of mono summing, left channel + right channel, hasn’t changed since and the technique has been a standard for a long time. The standard is well established but it hasn’t been questioned in more recent time."The aim with the study is to find out if there may be an alternative way to mono summing and if the conversion from stereo to mono can be done in way that would reproduce the material in a more authentic way."Alternative mono conversions have been evaluated in listening tests. The results shows no major interest for an alternative mono conversion. It is still difficult to tell whether there might be a better way to mono summing and more research has to be done with other conversions, more songs and genres.
