Bit Depth vs. Bit Rate in Audio Recording

One measures speed; both show quality

The terms bit depth and bit rate are so similar in digital audio that many people assume they mean the same thing. It’s easy to confuse the two, but they’re different concepts. To reduce some of the confusion, we’ve compared bit depth and bit rate.

General comparison

Shallow

  • Determines the audio fidelity.

  • Controls the amount of data contained in audio files.

  • This affects clarity and detail.

Debit

  • A measure of bandwidth in audio files.

  • This affects the playback quality.

  • Factor determining file size.

You may need to know the bit rate when choosing the best audio format for your portable device or converting to MP3 with an audio converter tool or another program such as iTunes.

Bit depth becomes important when digitizing your analog music collection or when you need the best possible sound quality.

Advantages and disadvantages of bitrate

Advantages

  • Sets the total number of data bits specifying the quality.

  • Check the size of your files.

  • It’s a measure of bandwidth, so you’ll need a connection to support it.

Disadvantages

  • It does not detail a lower quality recording or ripping.

  • I cannot determine the amount of data in the file.

Bit rate is a measurement expressed in kilobits per second (Kbps), or thousands of bits per second. Kbps is a measure of the bandwidth of data transmission equipment. It shows the amount of data flowing through a network at any given time. For example, a recording with a bit rate of 320 Kbps is processed at 320,000 bits per second.

You can also express bit rates per second in other units of measurement, such as megabits per second (Mbps) and gigabits per second (Gbps). They are only used when the bits per second reach or exceed 1000 Kbps or 1000 Mbps.

High bitrate recording provides higher quality sound and takes up more space on a computer or mobile device. However, unless you have high-quality headphones or speakers, you’re unlikely to notice any improvement in quality over lower quality. For example, if you’re listening with a standard pair of headphones, you probably won’t notice the difference between a 128 Kbps file and a 320 Kbps file.

Advantages and disadvantages of bit depth

Advantages

  • Checks the accuracy of a record.

  • Determines the level of detail for the recording.

  • It determines the amount of data defining the sound.

Disadvantages

  • It does not add details to a file that is not already there.

  • I can’t control the amount of bandwidth required to play a file.

At first, bit depth may seem like a complex issue. In its simplest form, it measures how accurately a sound is represented in digital audio. The higher the bit depth, the more accurate the digital audio will be.

You’ve probably come across songs from MP3 download services or music streaming sites at a certain bitrate, but not much has been said about bit depth. However, if you plan to digitize your collection of vinyl records or analog tapes to store them as high-quality digital audio files, you need to know about bit depth.

A higher bit depth provides a more detailed sound recording. Low bit depth causes clipped sounds to be lost.

The bit depth measurement is in bits. For each 1-bit increment, the recording precision doubles. The higher the bit depth, the better the recording sound.

Audio CDs use 16 bits per sample, while Blu-ray discs and DVDs use 24 bits per sample. The sound quality obtainable from a Blu-ray disc or DVD is superior to that obtainable from an audio CD.

This attribute affects the amount of detail you can capture from the original recordings. The correct bit depth setting is also very important to minimize background signal interference and affect recording volume.

The final decision

In general, bit rate is a relevant concern when working with audio. Why? With CDs, you have very little choice. CDs are 16 bits per sample. It will be more important to maintain a high throughput.

Blu-ray audio is gaining ground. It allows for greater bit depth and ultimately more detailed sound. You can’t find all the Blu-ray release artists yet, so this is kind of a special occasion.

The most practical thing you can do to ensure your digital audio is of the highest quality is to use lossless formats such as FLAC and WAV.

Bit Depth vs. Bit Rate in Audio Recording

One measures speed; both indicate quality

The digital audio terms bit depth and bit rate are so similar that many people assume these terms mean the same thing. It’s easy to confuse the two, but these are different concepts. We compared bit depth and bit rate to help reduce some of the confusion.

 Lifewire Overall Comparison
Bit Depth

Determines audio fidelity.

Controls how much data is in audio files.

Impacts clarity and detail.

Bit Rate

Measure of bandwidth in audio files.

Impacts playback quality.

Factor in determining file size.

You might need to know about bit rate when choosing the best audio format for your portable device or when converting to the MP3 format with an audio converter tool or another program such as iTunes.

Bit depth becomes important when digitizing your analog music collection or needing the highest possible sound quality.

Bit Rate Pros and Cons
Advantages

Sets the overall number of bits of data, determining quality.

Control the size of your files.

A measure of bandwidth, meaning you’ll need a connection to support it.

Disadvantages

Doesn’t detail to a lower quality recording or rip.

Can’t determine how much data is in the file.

Bit rate is a measurement expressed in kilobits per second (Kbps), which is thousands of bits per second. Kbps is a measure of the bandwidth of data transmission equipment. It shows the amount of data that flows at a given time across a network. For example, a recording with a 320 Kbps bit rate is processed at 320,000 bits per second.

You can also express bit rate per second in other units of measurement, like megabits per second (Mbps) and gigabits per second (Gbps). These are only used when the bits per second meet or exceed 1,000 Kbps or 1,000 Mbps.

A high bit rate recording delivers better quality audio and takes up more space on a computer or mobile device. However, you aren’t likely to notice the improved quality over one of lower quality unless you have high-quality headphones or speakers. For example, if you’re listening over a standard pair of earbuds, you probably won’t notice the difference between a 128 Kbps file and a 320 Kbps file.

Bit Depth Pros and Cons
Advantages

Controls how accurate a recording is.

Determines the level of detail in the recording.

Dictates how much data describes the audio.

Disadvantages

Doesn’t add detail to a file that wasn’t already there.

Can’t control the amount of bandwidth needed to play a file.

At first, bit depth might seem a complicated subject. In its simplest form, it measures how precisely a sound is represented in digital audio. The higher the bit depth, the more accurate the digital sound.

You probably encountered songs that come at a particular bit rate from MP3 download services or streaming music sites, but little is said about bit depth. However, if you plan to digitize your collection of vinyl records or analog tapes to store them as high-quality digital audio files, you need to know about bit depth.

A higher bit depth gives a more detailed sound recording. A low bit depth causes quiet sounds to be lost.

The measurement for bit depth is bits. For each 1-bit increase, the accuracy of the recording doubles. The higher the bit depth, the better the recording sounds.

Audio CDs use 16 bits per sample, while Blu-ray discs and DVDs use 24 bits for each sample. The sound quality achievable on the Blu-ray disc or DVD is higher than can be achieved on an audio CD.

This attribute influences how much detail you can capture from the original recordings. Getting the bit depth right is also critical for keeping background signal interference at a minimum and affecting the volume of recordings.

Final Verdict

Generally, the bit rate is a relevant concern when working with audio. Why? You have little choice with CDs. CDs are at 16 bits per sample. Keeping the bit rate high will matter more.

Blu-ray audio is gaining traction. It allows for greater bit depth and, ultimately, more detailed audio. You won’t find every artist releasing on Blu-ray just yet, so it’s a special case type of situation.

The most practical thing you can do to ensure your digital audio is the highest quality is to use lossless formats like FLAC and WAV.
