iPhone as Audio Recorder

You never know when you might need to whip out a Portable Audio Recorder, so in that situation Vimeo member Alex Campbell introduces some very inexpensive (or free version) iPhone software that allows for some pretty neat audio recording tricks. Of course you'd need an iPhone for this to work. A few cool features are the built in Gain Controls and Hiss Reduction filter. Alex also links over to a company that sells adapters to input other microphones to your iPhone such as the Rode VM. Very cool if you're in a bind and already have an iPhone, just make sure you don't receive a call.... [Thanks Alex]

    A little late arriving to this post... but has anyone tried this with the ipod touch? is there any reason to think that it would not work in the same way?

    Thanks for the tip!

    Man, some shooters I know would have given ANYTHING to have this as an option just 10 yrs ago. (by that I mean, plugging in a pro-mic, and being able to store and visualize the recordings)

    I noticed the free version had a ton of gain, even when the gain slider was fully turned down, I'm wondering if any of the pay version presets eliminate this. Considering putting my NTG-2 through my Juiced Link Preamp and into my Ipod and giving it a try. It could just be the poor mic on the Ipod causing the hiss.

    I used my iPhone and VideoMic the other week for recording audio and it came out great. Not perfect, but good enough that only the trained ear would notice.

    If you put your iPhone in airplane mode you wont have to worry about a call or text 🙂

    Hi, this is my video.
    In the video, I was actually running the iPhone directly into my 5D. There was no need to change anything at all. You can use it as a field recorder, but there is a function of the app, which I have not seen anywhere else, to pass through a signal. This allows real time monitoring of the audio coming in. From there, I turned down the manual audio level to 5 clicks above the bottom and controlled the level into the camera using the headphone volume on the phone.
    In my Vimeo account, I have linked to a site called KV connection that sells an adapter that allows you to input a mic and monitor via 3.5mm jacks. This means you could potentially use any sort of mic, feed it through the phone as a preamp and then input it into the camera using a variety of real time filters, analog gain etc. You could also then disconnect the phone, use it as a field recorder and then sync it with your video in post.

  7. @Darryl you don't have to speed it up, it's more of a re-sampling thing. Your editing software should handle it pretty easily. Speeding up and slowing down audio (i.e. pull-up / pull-down) was necessary when transferring film projects to videotape for editing. In an effort to over-simplify... you don't need to worry about it too much since you're file-based. The software should do it automatically.

    Most NLEs will automatically conform audio to match project settings. Failing that, a sample rate change is a breeze with Audacity.

    One more thing to add... using it's highest setting, it records at 44.1 kHz so the audio files will have to be sped up to 48 kHz to sync any Canon DSLR footage. Not sure how hard this would be... any ideas?

    Airplane mode would resolve the in coming call issue. Gonna have to try this to see how good the quality is.
