Background Sound Recorder v2.38 [Paid] Apk [Latest Version]

The free version of the Background Sound Recorder app

IMPORTANT! This is an evaluation version, the app’s capabilities are limited intentionally!

✓ Phone call recording is enabled, but limited to the first 3 minutes of each conversation

✓ In the sound recorder mode, only three duration options are available: 1, 5, and 20 minutes. If you choose 20 minutes, the “Continue recording” option will be turned off, a new recording will not be started after the 20-minute recording is finished. The full version does not have this limitation, and has more duration options.

✓ Only two sampling rate options are available: 8 and 48 KHz. This should be enough to test the capabilities of your phone’s mic. The full version has a wide variety of sampling and bit rates to choose from.

✓ No automatic uploading to Google Drive. However, you still can upload to FTP or Dropbox!

Short description of the features:

✓ Two recording modes: 1) Microphone recording 2) Phone call recording

✓ Very high maximum sound quality: can be set up to record at 48KHz

✓ Wide choice of optimized sound quality settings: from the most efficient to the most detailed

✓ Can record phone calls from the microphone to bypass the Android 6.0 restriction of the VOICE_CALL audio source

✓ Other sound recording apps will not work with other phone call recording apps because on Android, only one app can record something at a particular moment. Thus, it’s best to use one app for calls and microphone recordings. The app will yield the audio subsystem to phone call recording when a call is made, and return to microphone recording when it’s done

✓ Can record while the app is in the background, you can pretend that you aren’t recording anything

✓ Will automatically upload the recorded files to your preferred cloud storage:
++ Google Drive
++ Dropbox
++ FTP

✓ Can offload the recorded files to an SD card

✓ Starts on system reboot, continues recording (if started during the previous run)

✓ Saves space: can be set up to remove the oldest recordings if the total size exceeds a maximum

✓ Can record to the app’s private folder or to the common storage

✓ Record by schedule: time of day, days of the week

✓ No intricate procedures to start and stop recording: just open the app and click the appropriate button

✓ No accidental recording or accidental failure to record!

Problem: BSR records for a few hours in background, then stops.
Solution: Check your phone’s power saving settings. Make sure the BSR app is “protected” and is allowed to work in the background indefinitely.

Problem: BSR doesn’t start up when I reboot the phone.
Solution: Make sure that you had started the recording before you turned off the phone. Check if BSR can be found in the list of running apps (Developers’ Options) after startup (without clicking the BSR icon). Check your phone’s settings for “optimizations” that might block apps from running on startup. Try making the BSR app “protected”.

Problem: Very bad sound quality even on highest settings
Solution: Make sure that your microphone is not obscured. Check if a leather or plastic casing of the phone obscures any of its microphones. Record a short audio speaking or knocking to different parts of your phone to find out where the most sensitive microphones are located. If the mic is on the bottom, put the phone up side down in the pocket so that the mic sticks out. Try an external microphone. Try a different phone, more expensive phones tend to have better microphones.
