Certainly, peak meter is valid to clip detection.\r\nHowever, on the other hand, I think peak meter is not suitable for \"volume monitoring for instruments\" .\r\n\r\nI recommend the \"loudness meter\" for volume monitoring during the session.\r\nLoudness meter indicates the sensory loudness for the human ear.\r\nIt should be suitable than the peak meter as a guide for the volume adjusting.\r\n\r\nhttp://crasher.orz.hm/ninjam/files/loudness1.mp3\r\nI've prepared a very extreme example.\r\nThese are \"very thin drum\" and \"very fat guitar.\"\r\nThe drum is a dry sound with no VSTeffect. It is peaky and attacky.\r\nThe guitar is heavily compressed sound with many VSTcompressor and limiter. It has been crushed the attack.\r\n\r\n![loudness1](https://cloud.githubusercontent.com/assets/15982547/13500096/4d6e03ce-e1a4-11e5-905d-80ba22c5df11.png)\r\nTheir peak is the same. Both are -0.3dB.\r\nBut, ear sensation (loudness) volume is completely different. Guitar is terribly noisy.\r\n\r\nAs in this case, even if the peak value is the same, their feel volume is not necessarily the same.\r\nTherefore, I think that the peak meter is not optimal standard of volume control in NINJAM session that appeared a lot of kind of sound. ,\r\n\r\n\r\nI compared their loudness volume using loudness meter.\r\n\r\nLoudness volume of the drum track was about 3.\r\nLoudness volume of the guitar track was about 17.\r\n\r\nSo I modified the guitar volume \"-14 dB\".\r\n![loudness2](https://cloud.githubusercontent.com/assets/15982547/13500116/5f8f7ce0-e1a4-11e5-95bc-78cbc1c15ba6.png)\r\n\r\nThis is the result.\r\nhttp://crasher.orz.hm/ninjam/files/loudness2.mp3\r\n\r\nI feel this is a good volume balance.\r\nAs shown in this example, I think the loudness meter is a better volume control standard than the peak meter.\r\n\r\nIf NINJAM Client has built-in loudness meter, and musicians decide the recommendation loudness volume range beforehand,\r\nWe will be able to volume decisions based on better criteria. By doing so, volume balance of the NINJAM session will be improved easily."},"comment":{"url":"https://api.github.com/repos/elieserdejesus/JamTaba/issues/comments/191836730","html_url":"https://github.com/elieserdejesus/JamTaba/issues/266#issuecomment-191836730","issue_url":"https://api.github.com/repos/elieserdejesus/JamTaba/issues/266","id":191836730,"user":{"login":"elieserdejesus","id":1012741,"avatar_url":"https://avatars.githubusercontent.com/u/1012741?v=3","gravatar_id":"","url":"https://api.github.com/users/elieserdejesus","html_url":"https://github.com/elieserdejesus","followers_url":"https://api.github.com/users/elieserdejesus/followers","following_url":"https://api.github.com/users/elieserdejesus/following{/other_user}","gists_url":"https://api.github.com/users/elieserdejesus/gists{/gist_id}","starred_url":"https://api.github.com/users/elieserdejesus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/elieserdejesus/subscriptions","organizations_url":"https://api.github.com/users/elieserdejesus/orgs","repos_url":"https://api.github.com/users/elieserdejesus/repos","events_url":"https://api.github.com/users/elieserdejesus/events{/privacy}","received_events_url":"https://api.github.com/users/elieserdejesus/received_events","type":"User","site_admin":false},"created_at":"2016-03-03T16:24:32Z","updated_at":"2016-03-03T16:24:32Z","body":"Hi @NakajimaYusuke , I totally agree with you, peak meter is usefull only for clip detection, and is almost useless in a \"mixing\" scenario.\r\nI'm scheduling this issue for the next release, but Jamtaba development is in slow motion mode at moment :)"}}
