Im thinking a dedicated battery supply for the mic might be the best thing. In the case of an external device it will attempt to power it ,
If the phone detects external power it will attempt to charge off it ,and engage those circuits, creating extra noise The other issue is phone battery drain due to the mic compromising the recording time , Theres a spiral metal screened cable available in the bargain store, all the usual types of connection are covered ,USB C ,lightening etc They might have better screening than the usual foil with drain wire or unscreened. Id prefer to separate the phone and mic by a few feet via an extension cable ,
The mounting style of the phone and mic is orientated towards camera work the device horizontal on the hot shoe mount. It does appear to have a gold plated membrane , Its hard to see the precise details of the capsule as theres what looks like silk mesh behind the wire screen ,

When its plugged into the phone you get a pop up asking to connect to the internet to download the Rode app from the store. It comes with 3 different rubberised mounts that corresponds with the various model of iphone thickness. Just like every other Rode the standard of the engineering is first class ,
The Apogee Duet 2 looks like a good option for an external audio interface, 2 mic/line/inst inputs and 4 outs, it seems like the device is still supported by Apogee in iOS.
Tonegenerator two tones with pause portable#
The Rode I-XY seems like the perfect add-on to turn the iphone into a portable stereo recorder, the Iphone itself cost nothing, its an older model but still has more than enough processing power for the job and gives it a reason not to get dumped or sit in a drawer unused. Lets take an example, suppose I want a nominal 440hz tone ,44.1khz, 24 bit ,am I better off in terms of accuracy to go with 441hz as it neatly divides into the sample rate ? Is there a simple way to create accurate tones myself ?Ĭhoice of sample frequency, bit depth, fundamental frequency, level and duration or number of cycles, so I can quickly create bit perfect wav files and not simply sample rate convert or dither pre existing tones ,which might lead to inacuracies. Ive been looking around for wav file test tones to download, there are a few available from audio manufacturers and other online sources for test purposes, they typically are quite limited.
