In today's time, the trend of podcasts, voiceovers and audio content creation is increasing rapidly, and our visually impaired friends are also not far behind. Creating content has now become very easy with the help of Assistive Technology and modern Accessibility Settings. Supporting this creativity, Tech Assistant for Blind (which is a great Accessible Android App) has come up with an amazing Audio Mixer feature. This tool helps users using TalkBack to mix audio professionally. Let us know how you can take your audio projects to the next level with this Accessible Feature

## What is Audio Mixer? (What is this feature?)

Audio Mixer is a very powerful tool. Generally, audio editing apps are very difficult to use for visually impaired people because their layouts are not Screen Reader friendly. And even if an app is found, it does not have advanced settings as per our requirement, due to which we have to install different applications to mix audio. But this feature of Tech Assistant for Blind app is completely designed keeping Accessibility in mind. With its help, you can mix two different audio tracks (for example, one is background music and the other is your voice or voiceover) together. In this, you can control the volume of each track separately, set delay in them, do trimming and create a professional output file by combining both.

## Key Benefits of this feature

  • Independent Audio Editing: With the help of this feature, Blind users can mix voiceovers for their audio files, podcasts or YouTube videos on their own without taking anyone's help.
  • Precise Control over Tracks: You can mute, delete, or increase or decrease the volume level of each track individually.
  • Advanced Delay and Loop Options: If you want to start a track after some time, or want to play any background music continuously, then this work is done in just a few clicks.
  • Isolation Preview: Before mixing, you can listen to any one track alone, so that there is no mistake in editing.
  • Multiple Output Formats: This feature lets you export audio to many popular formats like MP3, AAC, M4A, WAV, FLAC, OGG, and OPUS.
