Audio processing and ALC in the FT-897D. I recently bought an FT-897D, and after a period of operation noticed. problems with what I perceived to be a low average level of output power and. reports of muffled audio. This is the story of my investigation to improve the. audio quality and increase the average level of transmitted power.
Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel. For example, English suffix-s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs).
WMA Pro, a newer and more advanced codec, supports multichannel and high resolution audio. A lossless codec, WMA Lossless, compresses audio data without loss of audio fidelity (the regular WMA format is lossy). WMA Voice, targeted at voice content, applies compression using a range of low bit rates.
