Formats

There are three sound formats usable in blippar: .OGG, .MP3 and .WAV.

 
 

.OGG

This is the recommended format to use - compact and low processing overhead on the device. Being a compressed format it is not advisable to re save these files, for any alterations use the original source.

 
 

.MP3

The most common one used - compact and with decent quality for mobile devices. Being a compressed format it is not advisable to re-save these files. For any alterations, use the original source.

 
 

.WAV

This format has a perfect, clear sound, but has a huge file size on the device, even though they compress in the zip archive sent to the user very well. To be used only in very special cases – for example, modulating the sound corresponding to the tilt of the phone like a gas pedal.

 
 
Note that sound in blippar cannot be streamed like videos and must be included in the files list to download with the blipp.

The ideal program to export sounds is Adobe Audition.
