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. Also, external microphones are supported.

• Records and plays mono or stereo wav files

• Supports file overwrite or resume record dubbing modes

• 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 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 (even if you have two or more SD cards installed). Default is SD card. Optionally makes recordings visible to your favorite player

• 9200 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 Play Store 2 hours return 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 uses the PlayLimiter and ignores the Monitor switch, so monitoring can be deactivated 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 auto start/stop control signal filter with 1.5kHz is optimized for speech. 750Hz are better with high-frequency environmental noise, 3kHz reduce low-frequency influence
• Soft Clipping is active above -3dBFS
• Limiting and Soft Clipping work only if Boost is greater than 0dB
• Recording Boost above 20dB might produce hardware feedback loop (caused by weak power supply)
• Overwrite and Append modify existing recordings (warning can be switched on/off)
• Activate flight mode to reduce noise floor

Love it, but... Did you know that if you change recording destination setting, all current recordings disappear? I found out that you CAN record to SD card using the preset \sd\android\data\whatever. It STILL killed all my current recordings after I tried to set an user-generated SD folder, and then switched it to one of the default ones again. After this, my recordings (not essential, thank God) were gone, so beware.

The best audio recorder app I tried I have a Nexus 5 and I tried about 5 or 6 different recorders, and this app provided the best quality and settings. I needed to tweak the settings quite a bit to get the best signal, but this app rocks! It's actually a limitation of Android itself that you can't directly control audio gain, but for most situations where the audio is quiet, this app works great. Unfortunately I haven't found any good audio app for android that works at loud rock concerts, because the base gain is simply not adjustable yet in the OS.

Awesome! I use this app. almost on a daily. I even got advise from the creators. I record in a very poor location. With this you would think it was studio recording. Plus you get to share with the world.

Good app, but issues with downloading WAV files To access WAV files via USB on my Android 4.2.2 device, I first have to run a media scan (reboot does the trick). The quick response by support made me adjust my rating from four to a full five stars!

... But I love this, I really do - It's one of my most useful and used apps BUT - We are in the 21st Century and we are still using 6 character dates in filenames!?? Remember how much people mocked the people who didn't back in 1999 and said "But who'd ever be so stupid as to do that again?" - It was only 15 years ago; how soon we forget. Go on, please add 20 in front of the date; even if it's just an option in the long-file-name section of the settings. Make you a deal, if you do, you get your five stars!
