With its assistance, you can minimize or even eliminate the background noise.Ĭlear audio is an important part of running a good live commentary feed. This program has numerous complex options for improving your streaming or recording performance, such as an audio mixer with per-source filters. This code also gives the same background noise.OBS Studio is well-known for being one of the most popular screen recording and streaming apps in the world. I also upload some examples shown in the below code. I just want sensor output real-time converted into an audio file. so I need a minimum 100 wave file that is store in the SD card. Sir, I continually measure distance so I have required many wave audio file which plays according to distance. Something like an SD card and the TMRpcm library It is coming from the Talkie library and there is nothing you can do about other than find some other way of generating your sound. It's related to bit depth and if you convert a high-quality recording to 8-bits you'll hear it. But, it sounds like noise and just like regular noise it's worse with quiet sounds, but it goes-away completely with digital-silence. Technically, it's distortion and it doesn't exist with silence. There is another special case called "quantization noise". But, like other kinds of distortion it's not there with silence. With silence there is no distortion.Ĭompression artifacts (from low-quality compression) are distortion that's a little different because the distortion isn't related to signal level (loudness). The "classic" example" of distortion is if turn-up the volume and try to get 150W out of a 100 Watt amplifier, or if you scream into a microphone and overload the preamp. "Distortion" is also unwanted sound added to the signal but it's usually worse when the sound is loud and it doesn't affect silence. Of course if you have a loud dog barking nothing is going to hide that. You might hear some hiss or hum with quiet signals but louder sounds will often mask (drown-out) the noise. Noise is worse when there is a "silence" or a low-level signal. It's a philosophical definition/difference. If you are trying to record a dog barking then that's not noise. You can also get electrical noise from the electronics such as hiss, hum, or buzz, etc. If you bump the microphone with the guitar that's also noise. For example, if you are trying to record yourself playing guitar and the dog starts barking, the barking is noise and the guitar is the signal. Even with the latest professional software, pros still record in soundproof studios with good equipment and radio & TV studios are soundproof, etc. Noise and other audio defects are easier to prevent than to correct. If that is not the source of your background noise then please post a sound sample of your words with the background noise. If you still here this "background noise" then it is coming from the Talkie library and there is nothing you can do about other than find some other way of generating your sound. The way to tell is to just run one of the example files on an Arduino with nothing else going on. Linear predictive coding - Wikipediaīy its nature it will produce audio artifacts, which is what you might be thinking is background noise. This uses a system known as LPC ( Linear predictive Encoding ) which is an ultra compression technique like an early MP3. OK now the key thing that your software tells me is that you are using the Talkie library to generate your sounds. I have used a Lightware distance sensor and Wireless Digital Bluetooth Audio Transmitter(Amazon)
