Visuals drive multimedia content. However, audio is needed to engage the audience longer. 

Audio takes the form of voice-overs, background scores, or standalone content formats (podcasts and songs). Whenever audio is included, it requires special care to ensure the right quality and volume of audio is produced without overpowering the visuals.

Thus a reliable audio editing software is required. One can undoubtedly record live audio and use that. But to fine-tune the audio, a software can help significantly. Sound editing software can reduce noise, amplify low or high tones, cut, extend, or merge audio clips as required. 

There are many advanced tools available that only edit audio, and they produce excellent results. Most of them are paid though, and not every content creator has the budget to invest in audio editing. 

To help you filter these tools, we have created a list of the top 7 free audio editing software in 2021. 

But before we jump into the best free audio editing software, let’s discuss what you should consider when looking for a sound editing software.
