Vlada: We used a special artificial measuring head to capture the image of the headphones which we believe is currently the best way to do this. The sound of the earbuds in MixChecker is really weak – but it is a deliberate choice to try and get a realistic picture of what the average people would hear often using the earbuds that come bundled with their smartphones etc. We deliberately did not include any kind of hi-end audiophile earbuds because that wouldn't reflect what the average user is likely to have. Jakub: in our experience, MixChecker users are more than likely to choose their headphones very carefully. PTE: One of the comments we have heard is people saying that they have never had such terrible sound from my earbuds so why do I need MixChecker. Then we discussed the measurements with audio professionals and professional musicians at The Academy of Performing Arts, so we were able to collate a lot of great feedback, to help us refine the measurements. We made well over 300 measurements instances to create the MixChecker models. Each device was measured in echo-free chamber from several distances with different microphone positions. Vlada (Lead Programmer for MixChecker): We used professional software with DSP toolboxes. We then processed the results using complex techniques, even writing an application, to analyse and process the characteristics from all the measured results.Įven though MixChecker is based on a convolution engine, there is a lot of other work that has gone into the final product. We have used the best possible conditions for measurements and a professional system which costs thousand times more than the best audio interfaces. PTE: Because it uses typical characteristics, is it professional? We wanted to create just one typical characteristics of each device by combining the measurements, and it was not easy. We use the same underlying technology with our guitar speaker simulator products like ampLion Pro and GK Amplification 2, in which you may change the mic position using three parameters, but this is exactly what we wanted to avoid when creating MixChecker. But all smartphones have some similar sound parameters and so we designed MixChecker to give you some realistic picture. For example: if you are mixing an advertisement that will mostly be viewed on smartphones – you cannot determine what particular type of phone will be the most used one. MixChecker should be considered a guide that shows you the weaknesses of your mix when listening through various types of devices. Our aim with this tool is not to create a real model of particular device as such. Lubor (CEO): Mixchecker does not simulate every device on consumer market precisely, that just wouldn't be possible or practical. So we thought let's make something, that would make life easier. When we discussed the topic within the Audified team we realised that other people had similar problems. They mix not only for TV, but for radio stations, computer games, mobile OS games etc. Our solution was to use a TV set as a reference monitor but it was a hassle and we really wanted to find a quicker way to get to better sound. For example, I used to work in TV Promotion business and we ere often finding that our TV trailers sounded great in the studio but listening from a TV set they weren't so good. Jakub (Marketing Director): Our team developed the technology for MixChecker quite a long time ago for use on some of our other products. The idea for MixChecker itself comes from our experience in previous jobs. PTE: Where does the idea for MixChecker come from? When we talked to the team at Audified we found they were getting similar questions too and so we thought it would be best to try and answer these questions and also give you an insight into how this plug-in was developed along the way. When we announced MixChecker and then have reviewed it as well, some people have been unsure about whether MixChecker from Audified is a good idea, or if it even works.
