Digital Audio Aliasing

 

Introduction

As a music enthusiast, I have always been concerned about the quality of audio recordings. Two common problems that affect audio quality are aliasing and harmonic distortion. Aliasing occurs when the sampling rate of an audio signal is insufficient, causing high-frequency signals to be incorrectly represented as lower frequencies. On the other hand, harmonic distortion occurs when the amplitude of a signal is altered due to the presence of harmonics. In this article, we will discuss ways to prevent these issues and improve audio quality.

What is aliasing and how to prevent it?

Aliasing is a common problem in digital audio, but it can be prevented by increasing the sampling rate of the audio signal. As a general rule, the sampling rate should be at least twice the highest frequency in the audio signal. For example, if the highest frequency in the audio signal is 20 kHz, the sampling rate should be at least 40 kHz. By increasing the sampling rate, we can ensure that high-frequency signals are accurately represented in the digital audio signal.

My personal experience

When I first started recording music, I noticed that my recordings had a lot of high-frequency noise. After doing some research, I realized that this was due to aliasing. I increased the sampling rate of my recordings, and the high-frequency noise disappeared. Since then, I have made it a point to always use a high sampling rate when recording audio.

What is harmonic distortion and how to reduce it?

Harmonic distortion occurs when a signal is altered due to the presence of harmonics. This can be caused by nonlinearities in the audio system, such as distortion in amplifiers or speakers. One way to reduce harmonic distortion is to use a high-quality audio system with low distortion. Additionally, using equalization can help reduce distortion in certain frequency ranges.

Quote from a book

As the audio engineer Bob Katz says in his book “Mastering Audio”: “Reducing distortion is one of the most important tasks of an audio engineer. Distortion masks the details in a mix and reduces the perceived loudness of the audio signal.”

Improving audio quality

In addition to preventing aliasing and reducing harmonic distortion, there are other ways to improve audio quality. One way is to use a high-quality audio codec when encoding audio files. Another way is to use a high-quality audio player or amplifier when listening to audio.

My personal opinion

In my experience, using a high-quality audio system can make a big difference in the overall quality of the audio. When I upgraded my audio system, I noticed that the sound was much clearer and more detailed.

Conclusion

Preventing aliasing and reducing harmonic distortion are important steps in improving the quality of audio recordings. By using a high sampling rate, a high-quality audio system, and equalization, we can ensure that our audio recordings are clear and free from distortion.

Final words

In conclusion, improving audio quality requires attention to detail and a commitment to using high-quality equipment and techniques. While there are many factors that can affect audio quality, preventing aliasing and reducing harmonic distortion are two important steps that can make a big difference.

Data rate refers to the data flow used by a video file in a unit of time, also called bit rate or bit stream rate.

Digital Audio Quality
Digital Audio Quality

The popular interpretation is the sampling rate, which is the most important part of image quality control in video encoding. Generally, the units we use are kb/s or Mb/s. Generally speaking, at the same resolution, the higher the code stream of the video file, the lower the compression ratio and the higher the image quality. The higher the code stream, the higher the sampling rate per unit time, the higher the data stream, the higher the accuracy, the closer the processed file is to the original file, the better the image quality, the clearer the image quality and the higher the decoding capability of the playback device is required.

Of course, the larger the code stream, the larger the file size. The calculation formula is file size = time X code rate/8. For example, a 720P RMVB file with a 1 Mbps stream of 90 minutes is common on the Internet and its volume is = 5400 seconds × 1 Mb/8 = 675 MB.

Generally speaking, a video file includes images and sounds, just like an RMVB video file, which contains video information and audio information. Audio and video have their own sampling methods and different bit rates, that is, the same video Audio and video file bit rate is not the same. And what we’re talking about is the bitrate of a video file, which generally refers to the sum of the bitrate of the audio and video information in the video file.

Taking the most popular and familiar RMVB video file in China as an example, VB in RMVB refers to VBR, which is short for Variable Bit Rate. The Chinese meaning is variable bit rate, which means that RMVB adopts dynamic encoding. In this way, a higher sample rate is used for complex dynamic images (singing and dancing, flying cars, wars, actions, etc.), while a lower sample rate is used for static images, and the resources are use rationally to achieve image quality and volume .Effect.

The most fundamental difference between code rate and sample rate is that the code rate is for the source file.

 

2. Sampling rate

Sample rate (also called sample rate or sample rate) defines the number of samples per second taken from a continuous signal to form a discrete signal, and is expressed in hertz (Hz). Sampling rate refers to the sampling frequency when converting an analog signal to a digital signal, i.e. how many points are sampled per unit of time. How many bits are in the data for a sample point? Bit rate refers to the number of bits (bits) transmitted per second. The unit is bps (bit per second). The higher the bitrate, the more data transmitted and the better the sound quality. Bit rate = sample rate x number of bits used x number of channels.

The sample rate is similar to the number of frames of moving images. For example, the sampling rate of movies is 24 Hz, the sampling rate of PAL format is 25 Hz, and the sampling rate of NTSC format is 30 Hz. When we play back the still images sampled at the same rate as the sampling frequency, we see a continuous image. In the same way, when a CD recorded at a sampling rate of 44.1 kHz is played back at the same rate, a continuous sound can be heard. Obviously, the higher the sample rate, the more coherent the sound will be heard and the picture will be seen. Of course, the sampling rate that human auditory and visual organs can distinguish is limited, which is basically higher than sound sampled at 44.1 kHz, and most people haven’t noticed the difference.

The number of digits in the sound is equivalent to the number of colors on the screen, indicating the amount of data per sample. Of course, the larger the amount of data, the more accurate the playback sound, so as not to confuse the sound. of the teapot with the train whistle. In the same way, it is more clear and precise for the image, so as not to confuse blood and ketchup. However, limited by the function of human organs, 16-bit sound and 24-bit image are basically the limits of ordinary humans, and the highest digits can only be distinguished by instruments.
