How to solve the problem of random errors when playing sound in uniapp

Recently, in the process of developing the uniapp application, there is a function of playing sound that needs to be implemented. During the implementation process, random playback errors often occur, which greatly affects the user experience. This article will describe how I solved this problem.

Problem Analysis

First of all, I want to look at the specific manifestations of errors in playing sound. I found that the random playback error behaves the same no matter whether it is on iOS or Android system, that is, when playing certain sounds, there will be a brief freeze or the playback will be skipped directly, which causes the user to have trouble listening to the sound. Can't feel the smooth experience.

After some searching and trying, I found that the most likely cause of this problem is the performance problem of the uniapp platform. uniapp itself is a multi-terminal development framework, which requires some underlying code to achieve adaptation and compatibility for various platforms. The running speed of this low-level code may not be ideal on some low-end devices, which leads to lag or skipping during sound playback.

Solution

Faced with this problem, I have also gone through a long period of groping, experimenting and trying. Finally, I finally found some feasible solutions:

1. Before playing the sound, check whether the sound has been loaded. If the loading has not been completed, continue to wait. The next sound will not be played until the sound is loaded.
2. Pre-convert the sound file to a format suitable for the platform, such as mp3 format on the Android platform, wav format on the iOS platform, etc.
3. Split the sound file into multiple parts and only play one of them at a time. Doing this helps reduce the size of each file and the stress of playing it.
4. Reduce the duration of the sound. Sometimes, we need to play some particularly long sounds, but doing so will affect the smoothness of the audio playback. Therefore, we can crop the sound and play only part of it.

Through continuous attempts of the above solutions, I finally found a relatively feasible solution. In practical applications, I combined these solutions, which not only solved the problem of random playback errors, but also improved the user experience of the entire application.

Summary

When developing uniapp applications, we need to always pay attention to the performance issues of the application. Only by optimizing the performance of the application to its best state can the user experience be improved and win more praise from users. The solution introduced in this article may not be perfect, but it helped me solve a troublesome problem and continue to optimize the performance of the entire application. In future development, I will continue to explore feasible optimization solutions to create a better user experience for users.
