APTX HD (aptX High Definition) is a high-quality audio format designed by Qualcomm that has a bit rate of 576 kbit/s, a sampling rate up to 48 kHz, and sample resolutions up to 24 bits. The codec has minimal compression losses, and losses occur where completely lossless coding is not possible due to bandwidth constraints. It can be transferred with low latency to Bluetooth devices, retains audio frequencies up to 20 kHz, and offers a dynamic range of 120 dB or more. Briefly, the APTX HD format is perfect for high-quality audio and is best for playing on Bluetooth devices. It plays perfectly on most recent Android devices but may not be properly supported on other platforms or certain Android phones. In such cases, you can use a good converter tool to turn it into a more common audio format with little to no losses.
The AST file extension stands for Astound Multimedia Files which are extremely rare. It may be used in audio, multimedia, or image files. You can play a .ast multimedia file only after converting it to more common multimedia formats using a video converter tool that supports it. The extension may be used in a game audio file used most commonly in Nintendo Wii video games to store in-game music. They are rare files with a very specific purpose, but you can play them after converting them into a common music file format such as MP3 using a converter tool. Adobe uses AST file extension to store image data, and Adobe image editing applications can open such files.
