Hello all,
I am new here and would like to ask you for an advice. I would like to develop a mobile app for Android and Apple tablets. This app shoul playseveral selected tones (e.g. 125Hz, 250Hz, 500Hz,...) and for every tone there should be different volume leves. The app should act like a "screening audiometer" or so.
Since there are many mobile devices on the market, I would like to avoid the internal DAC and user a external USB-C / Lightning converter to get the exact soung quality. I don't want any EQ, any added bass, or something like that. I would like to playback exactly what was recorded. I would like to use studio headphones. The volume on the output would be controlled by the app (ideally no converter on the external DAC/converter).
Portable size, max. desktop size. Price areound $150USD. Android and Apple compatible. Ideally something still available and not EOL. Design is not important.
Can you recommend me something?
Thank you in advance for any help or guidance.
PS: sorry for the poor description, I am not an audio pro
