WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft Corporation.
WMA data can be encoded using Windows Media® Player.
To encode WMA files, only use applications authorized by Microsoft Corporation. If you use an unauthorized application, the file may not work properly.
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at regular intervals and expressing the height of the wave at each reading in digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling frequency”. The larger the value, the closer the reproduced sound is to the original.
Speaker impedance
This is an AC resistance value, indicated in Ω (Ohms). Greater power can be obtained when this value is smaller.
Dialog normalization function
This function operates automatically during playback of Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS or
It automatically corrects the standard signal level for individual program sources.
Dynamic range
The difference between the maximum undistorted sound level and the minimum discernible level above the noise emitted by the device.
Downmix
This function converts the number of channels of surround audio to a lower number of channels and plays back according to the system’s configuration.
