The 3GPP2 defines the 3G2 (3GPP2 file format) as a multimedia container format for 3G CDMA2000 multimedia services. 3GPP2 stands for the 3rd Generation Partnership Project 2. 3G2 is quite comparable to the 3GP file format but uses less space and bandwidth. It also comes with some extensions and more restrictions than 3GP. Cell phones and other devices use 3G2 files to store videos and send and share multimedia content over the Internet. Although 3G mobile phones use 3G2 often, it works on 2G and 4G phones too. Similar video streams and most audio streams used in the 2007 3GP file type are compatible with the 3G2 file format. Additionally, 3G2 saves audio streams such as EVRC, EVRC-B, EVRC-WB, 13K (QCELP), SMV, or VMR-WB files. The 3G2 file format doesn't support the AMR-WB+ and HE-AAC v2 audio streams.
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.
