Select the microphone your phone uses when you record a video in Fimic Pro (to capture clearer audio) «Smartphones: Gadget hacks



When you record videos on your phone, you have two cameras, the rear camera and the camera Selfie camera to switch freely between the two. For microphones, you can have more than one, but unlike the cameras, switching between them is not easy. Filmic Pro solves this problem by isolating the microphones so you can choose the best option for the audio track.

Currently, Filmic Pro only supports internal microphone switching on the iPhone. If you're an Android user with multiple microphones on your phone, you'll need to wait for Filmic Pro to update the app in the Play Store before you can choose which microphone to record audio with. On iOS and Android, however, you can switch to an external microphone (Bluetooth or cable).

To start, tap the adjustment wheel at the bottom right and select "Audio." Here you will find your microphone options as the first menu in the window. Tap the arrows to move through the microphone options. If there are no arrows, this means that you can not select any of the internal microphones and no external microphones are connected.

On a newer iPhone model, you can choose between the lower microphones on the Lightning connector, the front microphone of the FaceTime or TrueDepth camera, and the rear microphone the True Tone flash. For an Android phone, it's just the "Camera Microphone" that the microphone near the back or selfie camera should use.

For both iOS and Android, you can wirelessly connect your microphone (or Bluetooth headset with microphone) so that it appears in the microphone dialer. On an iPhone, you must first switch to the "Bluetooth microphone" option in this preference field. Audio quality may decrease depending on the product. For example, an old pair of Bluetooth headphones only gives me a sample rate of 8kHz, making it flat and dull, and some sounds may not even be recorded.

Bluetooth headphones work great as makeshift lavaliers, but you can also buy Bluetooth lavalier microphones that connect directly to your phone without a receiver. There are not many options, but there are some solid ones.

For wired microphones, simply connect them to the 3.5mm audio jack, USB Type-C port or Lightning port. If it is a wired headphone headphone with a microphone, it will be displayed as a "headset microphone" or something similar. A Bluetooth microphone with a 3.5mm jack receiver is also displayed when connected and connected, and a cheap wired omnidirectional lavalier microphone is mounted directly to the phone and plugged into the headphone jack. In particular, Rode VideoMic Me's mini shotgun microphone has a headphone jack so you can hear what you're recording with headphones so you know exactly what you're recording. There are similar products that have a Lightning connector instead:

(Some external microphones may require a TRRS adapter to work with Filmic Pro.)

Which microphone you should choose depends on your recording. If you are using the selfie camera on an iPhone, try the front microphone as it points in your direction. When the sound needed to the side is off, use the bottom microphone of an iPhone pointing to the source. If you are using an external microphone, place the microphone as close as possible to your subject or use a directional microphone. In short, choose the microphone that comes closest to the sound you want to record, whether you're switching internal microphones or using external microphones.

Also in the Audio Settings panel is the audio format selector switch (iOS only) switching between PCM, AIFF and AAC formats. For both operating systems, you can select the sample rate, which can vary depending on the selected device and microphone. For example, I've seen options for 8 kHz (a Bluetooth headset), 16 kHz, 44.1 kHz and 48 kHz, but Filmic Pro can reach 96 kHz for certain microphones (like those that have a Lightning connection).

The other options displayed on an iPhone.

In this menu, you can also select "Video Only" for recording without sound. This is good if you are using an external audio recorder for sound recording instead. There is also a "voice processing" option that addresses audio frequencies in the human speech domain to better capture conversations and monologues.

And only for iOS there is the "Automatic Gain Correction" option, which is helpful when recording with the internal microphones. However, in order to adjust the gain levels automatically, you can record more background noise in this way.
