How to Convert 128kbps to 320kbps Audio: Is It Worth It?

Bitrate plays a brilliant role in determining the file size of music and sound quality. Measured in kilobits per second, it tells you how much data is processed every second during audio playbacks.

A higher bitrate means that the sound quality is better, but it also ensures that the audio file is large. This guide will introduce the major attributes of 128kbps and 320kbps and explain how to convert 128kbps to 320kbps.

Part 1: What are 128kbps and 320 kbps?

The bitrates of an audio file in the MP3 format are 320kbps and 128kbps. The bitrate will inevitably impact both the file size and the sound quality.

1. 128Kbps (Kilobits per second)

It is termed the low-quality bitrate or standard bitrate. It tends to compress the audio aggressively to help reduce the file size. The noticeable downside of 128kbps is the audio artifacts, including flat bass, muffled highs, and reduced clarity, especially with high-frequency sounds and complex music.

2. 320kbps

It remains the highest standard bitrate for MP3 files, producing near CD-quality audio while preserving the original recording's complete details. 320kbps offers a rich listening experience with better dynamic range, clarity, and depth. Beyond that, 320kbps has a larger file size than 128kbps.

Part 3: How to Choose 128kbps or 320kbps?

When selecting between 320kbps and 128kbps, it is important to learn about the differences between these two bitrates, depending on your requirements. The preferences could be for professional editing, casual listening, and saving storage space.

1. Sound Clarity

320 kbps offers superior audio quality, with clearer highs, better bass, and richer details. It is perfect for sound systems, speakers, and headphones that can reproduce enhanced quality. On the other hand, 128kbps could sound distorted or flat on good audio equipment. It is an appropriate bitrate for basic use like background music and spoken word recordings.

2. File Size

A typical 3-minute song at 320kbps will be about 7-8 MB, while the same song at 128kbps contains 3 MB. If the bandwidth or storage is low, going for the 128kbps could be an ideal gig.

3. Drawbacks

128 kbps will sacrifice the sound quality for compression, and as a result, it could be unpleasant to listen to and grasp. 320kbps asks for lost space, and it isn't necessary if you're listening to music in noisy environments with earbuds.

Part 4: FAQs about 128kbps to 320kbps

Q1. Can I convert 128kbps to 320kbps?

A1. You can convert the 128kbps to 320kbps using software like HitPaw Univd, but opting for this method won't improve the original sound quality. Even if the file is larger, the audio will still have some of the original 128kbps constraints. Upscaling the bitrate doesn't necessarily mean you'll be able to recover lost audio data.

Q2. Which is better, 320kbps or 128kbps?

A2. From a sound quality perspective, 320kbps is far better than 128kbps. It delivers a clearer and fuller sound with minimal compression artifacts. However, if you want to stream with limited data or store many tracks on a small device, going for 128kbps could be a better solution.

Conclusion

If you want to choose between the 128kbps and 320kbps, this guide could be helpful. Although 320kbps offers the richer sound, converting the 128kbps to 320kbps doesn't magically enhance the music; it will only increase the file size without improving the overall audio details. However, if you'd like to experiment by converting 128kbps to 320kbps, HitPaw Univd remains the best converter.

It supports audio conversion in multiple audio formats, and you can compress audio files using HitPaw Univd's outstanding compression features. This tool also allows you to access several audio editing techniques to improve the quality of the audio files.
