How to Recover Deleted Files from Voice Recorder: A Step-by-step Guide. Step 1: Connect your digital voice recorder to a computer. If your digital voice recorder uses internal flash memory, find a USB cable and connect. If your files are saved on a MicroSD card, load it to a card reader or adapter and then plug it into your computer’s USB port. Windows Voice Recorder is a simple, easy to use tool built into the Windows 10 operating systems to record audio. It is a great tool that you can use to record and save audio right onto your computer for use in an audio presentation or similar task. Similarly, Windows 8 and 7 utilized a similar tool called Sound Recorder.

FAQ
How do I…
Back up my recordings?
Your recordings are stored on your device, not in the cloud, and will not automatically transfer if you change devices. You can use an app like Dropbox or Google Drive to back up your recordings:
- Open the app and switch to the “Listen” tab.
- Select all of the recordings you wish to backup.
- Select the share icon from the action bar at the top of the screen.
- Choose the app you want to use for backing up your recordings.
- Wait for them to upload.
- If you have recordings in more than one folder, then repeat the above steps for all of the folders you wish to copy over to the new device.
You can also use an app like Dropsync to do this for you automatically.

Transfer my recordings to my computer?
It’s highly recommended to back up the recordings on your computer before opening or modifying them. Some phones have been known to corrupt the recordings when the person played them back directly from the device.
If you’re using Windows:
- Connect the phone to your PC with your USB cable.
- Make sure your phone is in USB or media storage mode.
- Browse to the phone from your computer.
- Locate the files; by default they will be stored in the “EasyVoiceRecorder” folder.
If you’re using a Mac:
- Download and install Android File Transfer before connecting the USB cable.
- Make sure your phone is in USB or media storage mode.
- Browse to the phone from your computer.
- Locate the files; by default they will be stored in the “EasyVoiceRecorder” folder.
If you can see files only on your device but not on your computer, then try restarting your device.

Use an external microphone?
On the latest Android devices, all you need to do is plug the microphone into your device’s headphone jack. Once the external microphone is plugged in, the device handles everything automatically.
To ensure that you do record from the external microphone, set Settings > Tuning > Microphone to “Main”.
See also:
Use Bluetooth mode?
To record with Bluetooth, first check your device settings and ensure that Bluetooth is enabled and that your microphone is paired and connected. In your Bluetooth microphone settings, ensure that “Media audio” is checked. Once that’s done, you can record from Bluetooth by returning to the app and setting Settings > Tuning > Microphone to “Bluetooth”.
Bluetooth only works with 8000Hz mono recordings. On some devices, Bluetooth is supported only for phone calls, and not for application audio.

Troubleshooting
I accidentally deleted a recording! How can I get it back?
Easy Voice Recorder doesn’t store remote copies of your recordings, so unfortunately, it’s unable to restore a deleted recording.
It may be possible to use the services of a data recovery specialist. The chances of a successful recovery increase the less you use your phone and the sooner this is done.
To help avoid this in the future, you can install Dropsync to automatically back up your recordings to Dropbox. For easier recovery of deleted files, you can also try Dumpster, a recycle bin for your Android device.
I can’t record at all! I always get an error about other apps using the microphone.
As these are all 3rd-party tools, Digipom unfortunately cannot provide any support or make any guarantees about their effectiveness.
Only one app may use the microphone at a time. If you encounter this error and nothing else seems to be using the microphone, please restart your device.
If the problem still persists, it might be caused by:
- Having a call recorder or radio recorder installed and configured to always run, or running an app like MagicJack.
- On some devices, Google Now’s voice detection may prevent other apps from using the microphone. Some custom 3rd-party launchers also listen in on the microphone.

I can’t record phone calls!
Easy Voice Recorder cannot record phone calls on most phones, as this is blocked by the hardware or by the operating system itself. As a workaround, you may be able to record the call by using the speaker phone and by trying different options under Settings > Main use.
I can’t save recordings to my SD card on Android 4.4+!
Beginning with Android 4.4 KitKat, full access to your SD card and other external storage is now blocked for all 3rd-party applications, like Easy Voice Recorder. This means that you won’t be able to create new recordings there. Your new recordings can only be saved in the app-specific folder assigned by Android, and these recordings will be erased if the app is uninstalled.
If you recently migrated from an earlier version of Android, your current recordings can still be played back from their old location even if Easy Voice Recorder couldn’t automatically move them to the new location for you. New recordings will need to be stored in the new location.
Due to bugs in Android 4.4 KitKat, Easy Voice Recorder may report folders on your SD card as writeable when they are actually blocked by the system.
I can’t send my recording via SMS or email.
If your recording is too large to send by email or SMS, then here are a couple of options you can try:
- Turn on compression under Settings > Advanced & troubleshooting > Compress PCM files when sharing, then try again.
- Use a third-party file sharing app, like Dropbox or We Transfer.

My recordings sound terrible!
On some devices, a hardware fault may cause poor recording quality or may cause recordings to sound like chipmunks. To improve the recording quality, keep the device away from noise and ensure that any sound-boosting options in the settings (i.e. xLOUD) are also turned off. You may also try turning off Boost volume (gain) by going to the Recording screen, touching the Filters icon (magic wand), and moving the boost slider all the way to zero.
Changing Settings > Sound quality to “High” and trying different options under Settings > Main use may help to fix these issues.
See also:
Parts of my recording are missing!
Some devices turn their microphones off when their screens go off, and Easy Voice Recorder cannot detect this on every device. For these devices, you will need to force the screen to remain on while Easy Voice Recorder is recording.
You can do this by going to Settings > Advanced & troubleshooting and setting Sleep mode while recording to “Allow dimmed screen” or “Leave screen on”.
See also:
The app keeps getting interrupted!
On some devices, the system will terminate running apps when the device goes to sleep. To keep the device awake, go to Settings > Advanced & troubleshooting and set “Sleep mode while recording” to “Allow dimmed screen”.
If the problem still occurs, turn off the device’s battery saver mode, and add the app to the battery optimization exception list. If a task killer is installed, the app will also need to be added to its exception list.

Where Does Voice Recorder Save

Huawei
all models
Many models may have a slight chipmunk effect when recording in AAC, and the internal mic may introduce distortion.
Motorola Droid
all models
Recording and playback may only work when the screen is forced on, in Settings > Advanced & troubleshooting > Sleep mode while recording.
The Droid RAZR is confirmed to have a recording problem with the AAC format, starting with Android 4.0 Ice Cream Sandwich. The phone inserts a gap into the recording every ten minutes. Versions of the firmware earlier than Ice Cream Sandwich don’t seem to have this issue.
Older Motorola devices may sometimes create recordings that sound like chipmunks.
Samsung
Note 4 and Note 4 Edge
Bluetooth recording can be problematic on these devices. On Android 4.4 KitKat, the recording may simply fail sporadically, and on Android 5.0 Lollipop, the recording may silently switch to the device microphone when putting the app into background mode or turning off the screen.
Sony
all models with xLOUD
xLOUD may cause loud recordings to be distorted, even when gain is turned off.

Microsoft PowerPoint offers features to record audio narration and export as a video. PowerPoint records audio slide-by-slide rather than in one continuous file, allowing creators to easily re-record a slide if they make a mistake or need to change something later. Exporting as a video and uploading to Kaltura or Canvas for streaming is advantageous since it standardizes file types, doesn't require a download to view, is in a format that can be captioned, and allows viewers to navigate more efficiently.
A recent update has made the process comparable on a Mac, but the specifics vary. Windows 10 instructions follow; Mac users can click the link below to jump to the appropriate instructions.
Windows 10 Instructions:
The following instructions explain how to add audio to your PowerPoint presentation on Windows 10 and export that PowerPoint as an MP4. The text instructions cover the same information as the embedded video below.
NOTE: If you have an older version of PowerPoint, you may need to update it to access the features described below. If you do not have PowerPoint, you can download it and other Microsoft Office products for free by going to office365.uwec.edu. If you have questions about updating or installing PowerPoint, contact the LTS Help Desk at helpdesk@uwec.edu or 715-836-5711.
