I went through the configuration tutorial [here](https://github.com/introlab/odas/wiki/Configuration), but I still have a hard time figuring out appropriate parameters.\r\n\r\nFor the raw data config, it gives an example as following,\r\n```\r\nraw: \r\n{\r\n\r\n    fS = 44100;\r\n    hopSize = 512;\r\n    nBits = 16;\r\n    nChannels = 8; \r\n\r\n    interface: {\r\n        type = \"file\";\r\n        path = \"mics.raw\";      \r\n    };\r\n\r\n};\r\n```\r\nI was wondering, what is the hopSize and nBits for the 16SoundsUSB, and how to set the Sample rate (fS) for the 16SoundsUSB (for example, I want to have the 16SoundsUSB with 16kHz, what should I do, do I need to update the firmware?).\r\n\r\nThanks in advance :)."},"comment":{"url":"https://api.github.com/repos/introlab/odas/issues/comments/402905554","html_url":"https://github.com/introlab/odas/issues/83#issuecomment-402905554","issue_url":"https://api.github.com/repos/introlab/odas/issues/83","id":402905554,"node_id":"MDEyOklzc3VlQ29tbWVudDQwMjkwNTU1NA==","user":{"login":"FrancoisGrondin","id":4040041,"node_id":"MDQ6VXNlcjQwNDAwNDE=","avatar_url":"https://avatars3.githubusercontent.com/u/4040041?v=4","gravatar_id":"","url":"https://api.github.com/users/FrancoisGrondin","html_url":"https://github.com/FrancoisGrondin","followers_url":"https://api.github.com/users/FrancoisGrondin/followers","following_url":"https://api.github.com/users/FrancoisGrondin/following{/other_user}","gists_url":"https://api.github.com/users/FrancoisGrondin/gists{/gist_id}","starred_url":"https://api.github.com/users/FrancoisGrondin/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/FrancoisGrondin/subscriptions","organizations_url":"https://api.github.com/users/FrancoisGrondin/orgs","repos_url":"https://api.github.com/users/FrancoisGrondin/repos","events_url":"https://api.github.com/users/FrancoisGrondin/events{/privacy}","received_events_url":"https://api.github.com/users/FrancoisGrondin/received_events","type":"User","site_admin":false},"created_at":"2018-07-06T02:18:36Z","updated_at":"2018-07-06T02:18:36Z","author_association":"MEMBER","body":"Hi!\r\n\r\nThank you for your interest in ODAS and the 16SoundsUSB hardware. To answer your questions:\r\n\r\n1) 16SoundsUSB supports 44100 samples/sec for the sampling rate, so you should make the acquisition at that rate. However, in the config file, you have the parameter general.mu.samplerate to 16000, and odas will automatically handle resampling :)\r\n2) hopSize can be set at 512 for raw.hopSize\r\n3) nChannels should be set to 16\r\n4) The number of bits (nBits) should be set to 32\r\n\r\nLet me know if this answers your questions!\r\n\r\nCheers"}}
