We selected and acquired a representative sample of the popular smartphones and tablets on the market as of June 2013. Smartphone apps were selected based on their ability to measure occupationally relevant sound level values. A total of 130 iOS apps were examined and downloaded from the iTunes store*, of those, 10 apps met our selection criteria. A total of 62 Android apps were examined and downloaded, however, only 4 apps partially met our criteria and were selected for additional testing. As a result, a comprehensive experimental design and analysis similar to the iOS devices and apps study above was not possible.

Android-based apps lacked the features and functionalities found in iOS apps. This is likely due to the iOS advanced audio capabilities compared to other platforms, the open ecosystem of the Android platform, and having so many different Android device manufacturers using different suppliers and components.

Good point, we do note in our study that with the introduction of iOS 6, Apple allows developers of audio apps to bypass the speech filters. Though not all developers have taken advantage of this feature.

I am an ear specialist. I believe that everyone should download a sound meter on their smart phone, and urge others to do the same. This would help to avoid the hearing loss patients I see daily.Can you help? I need a sound meter app for my web site and I am trying to find one that is

As a DIY experiment, perhaps you could build an oscillator with selectable output about 10 kHz apart, through the entire band of interest. If you got a microphone capable of responding in that range, you could amplify that signal with a filter to cut out the audio band, then mix it with oscillator output. Input that into a MIC jack and run an app with spectrum analysis (e.g. SPLnFFT). Then there should be peaks at difference frequencies. For example if there is ultrasound at 31 kHz and you mixed it with 30 kHz, you should see a spike at 1 kHz.

For purposes such as teaching a course, I would focus on precision of measurements instead of accuracy. One of the major issues with Android devices is that a very small percentage run the latest version of the OS. I suggest you have the students download a certain app (see table 9 in our expanded report -12a.pdf), ensure that they all have the same version (latest) of the Android OS, and see if you can use a single sound source to calibrate those phones, collectively, to a known sound level.

Unsupported media content cannot be streamed directly or transcoded and must be downloaded and viewed using a 3rd party Media Player. In most cases, the media is either not supported, ripped, pirated, contain multiple audio streams or has been converted from an unsupported media source. Converted, ripped and pirated media files are not supported. Only the native Codec is supported. Supported Web Browsers My Cloud OS 5 supports the following web browsers.

  • In the Snapper wave form you can select a part of the sound file and:drag it out, to create a new file.

  • drag it to any DAW, sequencer or audio editor

  • turn the selection into an mp3 file. (or m4a)

  • split interleaved stereo files into separate .L and .R file sets or vise versa

  • convert to m4a and attach it to an email in one go.

  • export to WAV (BWF, Broadcast Wave), mp3, or m4a (MPEG-4 audio).

All of them. Snapper opens over 50 sound file formats. That includes compressed files, split stereo, 192 kHz, 5.1 surround files, cds and videos containing audio. Snapper shows loops, markers, timestamps, regions, BWF annotations, even album covers. You name it, Snapper can handle it. For some formats you need to install external components, here's more on that.

Mostly video playback errors arise due to unsupported codec packs or device drivers. Sometimes the video file may also turn corrupt due to abrupt interruption during transfer/download/processing or a virus in the drive.

Most of the video errors are due to the absence of supporting codecs. The solution is to download a codec pack on your System so that you can play any video file type. Some popular codec packs are K-Lite, X-Codec pack, Shark 007 Codec pack, etc. You can download codec packs online by visiting their websites. Read More

Corrupt or outdated Display Drivers can create video playback errors. Troubleshoot playback issues by updating display drivers on your computer. You can do this manually through Device Manager on Windows PC.

Manual methods shared in the post can fix video playback errors and issues related to codec and graphic drivers on your computer. If you face video errors when trying to play online videos on a PC, ensure your browser is updated.

If you see this error message, download and open the file on your computer or phone to view it.Note: Previews will be generated only for the file types available to the file owner. For example, if a user on a Basic plan shares a .mxf file with a user on a Professional Plan, the user on the Professional plan will not be shown a preview, even though the Professional plan should allow previews for those file types. Check this article for file types that each Dropbox plan supports.

If you receive an email with a link to a Webex recording, just click on the link to watch it. There's no player required. Or if you've downloaded a file, get the Webex Player below (file types are .ARF or .WRF) for your operating system.
