![]() ![]() AAC can support a broader range of audio formats, including those that require a higher sampling rate. This bit-depth is sufficient for most applications, but some high-end applications that desire more accuracy and detail may require relatively higher bit depths.ĪptX supports 44.1kHz and 48kHz, whereas AAC supports a sampling rate of 8kHz to 96kHz. Both support a bit-depth of 16 bits of data meaning that each sample is represented using 16 bits. More clearly, a higher bit-depth in an uncompressed audio signal indicates that the codec has the potential to represent the audio signal during compression more accurately. In the case of audio codecs, bit depths help establish the level of detail with which an audio signal is compressed. This metric determines the member of bits used to represent the amplitude of an audio signal. A higher sampling rate captures more nuances in the music files, including subtle changes in volume or pitch.Īnother crucial metric is bit-depth. What comes out of this is a more accurate representation of the original sound wave. Normally the higher the sampling rate, the more samples in a second are taken. Basically, it’s the number of times per second either aptX or AAC records a sound wave and converts it into a digital signal. The sampling rate is a crucial metric in digital audio codecs because it determines the frequency or how often an analog audio signal converts into a digital signal after sampling. ©Sundry Photography/ Sampling Rate and Bit Depth AptX is a proprietary codec technology developed by Qualcomm, which is headquartered in San Diego, California. However, people also use it for digital radio broadcasting, mainly compatible with iOS devices. Below are the differences between aptX and AAC. Unlike aptX, AAC finds common use in streaming audio over the internet. AAC is an acronym for Advanced Audio Coding. On the other hand, AAC is an open-source codec often used in multiple audio compression applications. This technology finds use in various audio applications, including TV audio, music streaming, and video gaming. It uses a lossy compression algorithm that reduces audio size without affecting audio quality. The abbreviation aptX stands for audio processing technology. AAC: OverviewĪptX is a proprietary codec technology developed by Qualcomm. We’ve already established a few discrepancies from the above table, which we’ll discuss in greater detail in the following sections. However, first, let’s have a brief overview of aptX and AAC. ![]() While these technologies changed how we consume Bluetooth audio, they use different methodologies that yield varied results. Incorporating codecs in Bluetooth was a major milestone in wireless audio technology. Specificationġ.8 ms ms devices, Some Windows devices The following table overviews the technical specifications comparison between AptX and AAC. ![]() We’ll appraise their encoding methods, technical specifications, and performance characteristics to bring to light the best. However, some differences exist that make one codec technology better. As such, they ensure they achieve the highest possible audio quality while reducing the file size. Both promise high-quality audio and use advanced algorithms to manage the bitrate of the audio stream. Two popular codecs used for Bluetooth audio are aptX and AAC. The main objective of audio codecs is to produce high-fidelity sound at the least amount of bits without compromising quality. In a basic sense, an audio codec is an algorithm that compresses and decompresses audio signals. Part of what led to this development was the incorporation of new audio codecs. The audio side of Bluetooth, in particular, has received tremendous headway. The number of peripherals that use Bluetooth to communicate is immense - wireless keyboards, headsets, video game controllers, mice, you name it. Today, it’s a ubiquitous technology applicable in almost all hi-tech use cases. Bluetooth technology has come a long way since its humbling days as a wireless communication protocol that transfers data between mobile and fixed devices. ![]() ![]() ![]() **********Set your favorite hip hop sounds as ringtones and drop the bass****************Įveryone enjoys a good beat, right?
