In Windows XP, I used to use sndrec32.exe (Sound Recorder accessory) to open a wav file and the get properties on the file. This would display the length, data size, and audio format (e.g. GSM 6.10 8.000 kHz, Mono). There was also the option to convert the file to another format.

I can't find this functionality in Windows 7. What is an alternative (hopefully built in)? SoundRecorder.exe in doesn't have this functionality. I always wondered by sndrec32.exe did have that, but I would like to know where that functionality went.

Update: Based on the comments, it looks like Vista might have this information in the properties (I can't verify this). The properties of a WAV file in Windows 7 does not.


I've long used a small utility, the GSpot Codec Information Appliance. Don't ask me about the name. I didn't choose it. ;)

Anyway, you can drag most any type of media file, audio or video, into the app, or use the File|Open menu (it also supports batch processing) and it will tell you all kinds of information about the file.



  • This has the information I am looking for (and free). Thanks! – chrish Nov 19 '09 at 3:38

VLC media player can show information about wav files. In VLC's playlist, right click your wav file and select "Information...". Then, in the "Media Information" window that pops up, click the "Codec" tab. You'll see information like this:

Type: Audio
Codec: PCM S16 LE (s16l)
Channels: Mono
Sample rate: 44100 Hz
Bits per sample: 16

If you want an online, drag-and-drop way to get every piece of metadeta, specifications, etc., (actually a lot of info, see the screen-cap), use


It's a quick-and-useful alternative to MediaInfo, that one somewhat-inappropriately-named program in the accepted answer by @JMD, or other on-computer programs. All of those solutions are great solutions, by the way. The online, also gives you a lot of information. Here is an example of the information from an audio file I have called audio.wav - I recorded my voice for a little bit.

Metadata Information from get-metadata.com

The web-app I'm sharing is a "Free Online EXIF Viewer", meaning you can find stuff about videos and documents as well.

Hope it helps!


If you install Quicktime, it has an Info window that displays bitrates, channels and frequencies.

  • In Windows 7, I get the following: Title, Subtitle, Rating, Contributing artists, Album, Year, #, Genre, Length, Bit rate, Media created, Copyright, Parental rating, Parental rating, Name, Item type, Folder path, Date created, Date modified, Size Attribute, Offline availability, Offline status, Sared with, Owner, Computer. I am looking for codec, bitrate, mono/stereo. – chrish Nov 19 '09 at 3:37

The info is still there in the Details tab, just moved around:

audio format : in File / Item type.
length : in Media / Length
data size : in File / Size


I recommend you: https://mediaarea.net/en/MediaInfo

It shows all details about audio formats (bit depth, frequency, etc.). Works in Windows.
