Field Recorder is only available on Google Play!

Turn your Android into an HQ audio recorder!

Features

Field Recorder provides easy-to-use presets for standard tasks like dictation or concert recording. However, it is designed for professional use as it provides more than 80 options to customize it to the given device and situation.

⚫ Built-in and external microphones are supported and also 'class-compliant' USB soundcards with Android 5

⚫ Records and plays mono or stereo wav files

⚫ Supports file overwrite and resume recording

⚫ Convert your recordings to mp3, AAC or FLAC via free helper apps, share or send them

⚫ Up to 90 seconds pre- and 4s post recording. You won't miss any important stuff even if you are too late at the start button

⚫ Auto start, stop, and continue, depending on loudness. The control signal can be filtered independently to optimize it for voices and other audio signals

⚫ When recording, automatic stop at 4GB maximum file size and even seamless restart of a new file is available (activate auto start with a low threshold)

⚫ High-precision stereo audio engine with various low-cut filters, minimum-phase shelving equalizers and stereo balance correction to compensate for flaws of the microphones. Also with recording booster, configurable limiters, soft clipping, and high-quality monitoring

⚫ Wav player with volume maximizer, silent and audible fast-forward and fast-rewind, and low-latency random access to any play position via progress bar

⚫ Stores recordings internally or on any chosen SD card. Default is SD card. Recordings are visible to your favorite player

⚫ Almost 10.000 colors available for the metallic-brushed skin. Also, you choose round or rectangular LEDs, left-hand operation, the button size, and your favorite color for the LCD display

The First 2 Hours: Getting Started

Use the 2 hours refund period to test how audio recording works on your phone. Start with the presets which you select by touching "Factory". Probably, you find a preset in the cloud perfectly adapted to your smartphone!

Then try the different inputs from "In:MicA" to "In:MicE" (touch "In:MicA"). If you activate "Monitor", use headphones to avoid an acoustic feedback loop. Check without creating audio files, just by pressing the pause button, which activates the level meters. In the LCD you see a date/time string as the potential file name.

Hints
⚫ The name of a modified preset is shown in the LCD in gray
⚫ Play back can amplify low recordings by choosing e.g. "Play +20dB" without clipping due to a 2nd limiter. It ignores the Monitor switch, so monitoring can be disabled during recording
⚫ Touch "time/position/free" label to show remaining recording duration
⚫ Touch battery symbol to toggle between battery and CPU usage
⚫ Touch "CLIP" to reset clip LEDs
⚫ Touch meter to open its configuration menu
⚫ The meter shows peak amplitudes or the start/stop control signal
⚫ Active auto start overrules pressing the pause button
⚫ The 1.5kHz filter optimizes the auto start/stop control signal for speech. 750Hz is better for environmental noise with high frequencies, 3kHz with low frequencies
⚫ Soft Clipping is active above -3dBFS
⚫ Limiting and Soft Clipping work only if Boost is greater than 0dB
⚫ Recording Boost ≥30dB might produce hardware feedback loop if power supply is instable
⚫ Overwrite and Append modify existing recordings (warning can be switched on/off)
⚫ Activate flight mode to reduce noise floor

Stopped Working Looked very promising, but suddenly failed too open, even after system and app cleaning and reinstall. Will switch to Voice Recorder Pro at this point. Disappointing

Excellent! I was on a video shoot at work and all of our audio decided to take a dump on me in one form or another. Low batteries, missing cords, etc. I didn't have time to rent additional gear so I decided to use my phone with this app to record dialog of the talent. I placed the phone near the subject, hit record, and we were golden. Not only was the audio useable, the signal was on level with the pro audio gear that we use. Metering is key. The GUI could use refinement though. Chunky.

Perfect. This has replaced a portable digital recorder for most purposes. The only shortcomings are with my hardware (Nexus 4). Thoroughly recommend this app.

VERY nice! This is a very reliable and nicely featured recording app. I'm a sound engineer and musician and this app has all the features of a good stand alone recorder with the convenience of being on my phone. Works very well in stereo at 48KHz, 16 bit, uncompressed even with the internal mics on my Galaxy S6. Good job guys. Great app!
