The bitrate of an audio file determines its sound quality. In general, a higher bitrate means better audio quality, as it allows for more detailed sound. However, there are trade-offs to consider when deciding on the bitrate for an audio file. While a higher bitrate provides better sound quality, it also results in larger file sizes, which can be cumbersome for storage and streaming. On the other hand, lowering the bitrate reduces file size but may also decrease the sound quality to a noticeable extent.

What You'll Learn
Lower bitrates decrease network strain but compromise quality
Lowering the bitrate will decrease the strain on your network but will also compromise the quality of your audio or video stream. Bitrate refers to the amount of data being transferred into audio or video. A higher bitrate generally means better audio or video quality.
The bitrate of an audio file determines how detailed the sound is. The more detail, the better the sound quality. However, there are many factors to consider when it comes to audio quality. For example, uncompressed files will contain the most information and have the highest bitrate, whereas compressed lossy files will have the least amount of information and a lower bitrate. Lossy audio formats such as MP3, AAC, and OGG lead to a loss of audio data and use lower bitrates to provide quality sound and smaller file sizes.
The standard bit depth for CD audio is 16 bits, which provides decent sound quality despite a smaller file size. On the other hand, a bit depth of 24 bits will produce higher sound quality but will result in larger file sizes. A high sample rate and bit depth will produce rich and detailed audio but will also increase the file sizes and bitrate. For example, a 5-minute music file sampled at 256 kbps in .mp3 format will consume approximately 20 MB of storage space, while the same song at a bitrate of 128 kbps will consume approximately 10 MB.
While higher bitrates generally indicate better quality, there is a reasonable lower limit to audio bitrate. At 128 Kbps, audiophiles will notice a loss in quality, and below 96 Kbps, even untrained ears will notice that the music feels "hollow". Therefore, lowering the bitrate can help decrease network strain, but it will also compromise the quality of the audio or video stream.

Audiophiles will notice a loss in quality at 128Kbps
Lowering the bitrate does indeed lower sound quality. Bitrate refers to the amount of data being transferred into audio, and a higher bitrate generally means better audio quality.
Audiophiles will certainly notice a loss in quality at 128 Kbps. This is because the sound quality degradation becomes very noticeable around 128 Kbps. This is especially true if the listener has a quality setup, such as high-end systems or a good amplifier and speakers. However, if they are listening on Apple earbuds, for example, they may not be able to tell the difference.
The difference between bit rates that are closer together, such as 256 and 320 Kbps, is more difficult to hear. On the other hand, the difference between very low and high bit rates, such as 64 and 1411 Kbps, is much more noticeable. This is because the higher the bitrate, the more information is contained per second, leading to increased detail and fidelity.
Lossy audio formats, such as MP3, are heavily compressed and lose a significant amount of data during the encoding process, resulting in sound quality degradation. In contrast, lossless formats such as WAV and FLAC do not lose any data and provide exceptional sound quality.
It is worth noting that while a high bitrate is important, it is not the only factor in audio quality. The delivery method and hardware also play a significant role. For example, if listeners are downloading or listening to physical audio formats, a high bitrate is more feasible. However, if they are streaming, a slightly lower bitrate may be preferable to ensure effective streaming.

Uncompressed files have the highest bitrate
In general, a high bitrate means high-quality audio. A higher bitrate means that more data is being transferred into audio, which generally leads to better audio quality. However, a high bitrate does not always mean better audio quality. For instance, if listeners are streaming the audio, a lower bitrate is preferable so that the audio can be streamed effectively.
When audio files are to be processed, it is desirable to work from an uncompressed original. Processing a compressed file usually produces an inferior final result compared to creating the same compressed file from an uncompressed original. This makes lossy compression unsuitable for storing intermediate results in professional audio engineering applications. However, lossy formats such as MP3 are popular with end-users as the file size is reduced to 5-20% of the original size, allowing a megabyte to store about a minute's worth of music at adequate quality.
It is recommended to always keep the highest-quality files to future-proof against new technology. Future audio formats could require greater bitrates, and future connections or hardware could potentially deliver high-fidelity audio. It is always possible to convert uncompressed files into a new format.

Higher bit depth means more detailed snapshots
In digital audio, sound waves are represented by a series of snapshots or samples taken per second. The more snapshots taken per second, the more accurate the representation of the original sound wave. Each snapshot captures the waveform's shape at a given moment and its distance from the zero point, which is silence.
Bit depth determines the resolution of each snapshot, affecting the dynamic range and noise floor of the recording. It determines how precisely the amplitude of a signal is measured. The higher the bit depth, the more amplitude values are available per sample, resulting in more detailed snapshots. For instance, a 16-bit audio file can represent 65,536 levels of sound, while a 24-bit file can represent over 16 million levels. The higher bit depth provides more detail in quiet and loud parts of the music, resulting in a richer and more dynamic sound.
The sample rate is the number of snapshots or samples of audio taken per second, measured in hertz (Hz). It determines the frequency range and detail captured in the audio signal. The higher the sample rate, the more snapshots captured, resulting in a more accurate representation of the sound. A CD-quality audio file has a sample rate of 44.1 kHz, meaning 44,100 samples per second. Higher sample rates, like 96 kHz or 192 kHz, capture more details of the original sound.
Bit rate, which is calculated by multiplying bit depth by sample rate, is the number of bits used to represent one second of audio. It is measured in kilobits per second (kbps) and represents the amount of data transferred into audio, impacting audio quality and file size. A higher bit rate means more detail, similar to a high-resolution image with more pixels. For example, a 320 kbps MP3 file has a higher bit rate than a 128 kbps file, offering better sound quality with more clarity and detail.
To summarise, a higher bit depth means more detailed snapshots, as it increases the resolution of each snapshot or sample. This, combined with a higher sample rate and bit rate, results in a more accurate, dynamic, and detailed representation of the original sound.

Below 90Kbps, the human ear will notice a drop in quality
The bitrate of an audio file determines how detailed the sound is. A higher bitrate generally means better audio quality. However, there are several factors to consider when discussing audio quality. Firstly, the human ear can only perceive a limited range of frequencies and amplitudes, and this range decreases with age. Additionally, the equipment used to play the audio file, such as mass-market earbuds or headphones, may not be capable of reproducing the full range of frequencies and amplitudes present in a high-bitrate file. In such cases, a lower bitrate file may be preferable as it can provide a similar listening experience while reducing the file size and bandwidth requirements.
Another important consideration is the type of audio file and the method of delivery. Uncompressed audio files, such as those used on audio CDs, have the highest bitrate and provide the best sound quality. However, compressed lossy audio formats, such as MP3, AAC, and OGG, use lower bitrates to provide smaller file sizes while still maintaining good sound quality. These formats are commonly used for streaming services and online audio playback, where reducing bandwidth usage and improving streaming efficiency are crucial.
It is worth noting that while a higher bitrate generally indicates better audio quality, there is a point below which the human ear will notice a significant drop in quality. Specifically, at bitrates below 90Kbps, even untrained listeners will perceive a noticeable decrease in audio quality. The music may start to sound ""hollow" or lacking in detail. This threshold can vary depending on individual hearing capabilities and the equipment used for playback.
To ensure optimal audio quality, it is recommended to record and produce audio at the highest bitrate possible. This provides the best starting point for capturing and preserving all the details and nuances of the original sound. However, it is important to consider the trade-offs between audio quality and file size, especially when distributing or streaming audio content. By understanding the limitations of the delivery medium and the capabilities of the target playback devices, content creators and audio engineers can make informed decisions about the appropriate bitrate for their specific use case.
