Different Ways To Reduce Audio Background Noise

We all know how annoying it can be to listen to noisy audio.

Professionals who do speech-to-text transcription on a daily basis sure can relate to this matter.

Your audio quality matters when you are doing the transcription process, especially if what you are trying to transcribe is an important matter, such as a legal case.

If your audio is filled with loud background noises, not only that it will be hard for the AI to automatically transcribe your audio but also for a human to manually transcribe it.

So, how can you reduce background noise?

Obviously, the result of the magic wand is not perfect. However, it did reduce a lot of background noise.

To enhance your audio, you can also do these additional steps:

  1. Go to settings.
  2. Click on Voice Memos.
  3. Change the audio quality from compressed to lossless.

We tried to find a similar function for Samsung users but could not find any.

Therefore, we recommend you use other tools to reduce the background noise.

How To Have A Better Audio Quality

As we have mentioned earlier, your audio quality matters when you are doing the transcription process.

Whether you are using a tool or manually doing it, transcribing noisy audio is hard to do.

So, here are ways to have better audio quality.

1 - Speak Closer To Your Microphone

If you are having a conversation with someone, you would prefer that person to stand closer to you so you can hear that person better.

The same concept goes with audio recording - the closer you are to the microphone, the clearer you will sound.

Do not be shy and speak too far from the microphone!

2 - Invest In The Right Microphone

You may think that your phone microphone is enough. However, if you do speech-to-text transcription on a day-to-day basis, we really recommend you invest in a good microphone.

A good microphone can help you do your job easier as you won’t be questioning ‘what the heck did I or this person say earlier?’ anymore.

Here’s a list of the best microphones for recording by Tech Smith.

3 - Choose The Right Spot

The quality of your audio recording can also be affected by your location.

Of course, if you are in a noisy room, it is hard to avoid noise.

But, if you are in a location where you can choose where to record, try to avoid areas with these items:

  • Fans
  • Refrigerators
  • Open Windows
  • Electronic devices
  • Washing machine and dryer

Advice To Professional Transcribers

If you are a professional transcriber and are invited to an event where there is a lot of noise all around you, we really recommend you also take notes.

Of course, we understand that in some instances, you probably can’t take notes. But if you could, we highly recommend you do so.

Writing notes will allow you to ensure a high-quality transcription, especially when there is a lot of background noise.

Sometimes, it is easier to decipher what a person is saying when you listen to it on the spot compared to listening to a recording
