TL;DR: Noise reduction algorithms are compared against various noise reduction methods and best ratio was obtained for Spectral Gating Algorithm.
Abstract: Podcast allows recording of audio file on any topic. It is like an interview where one person questions and another person replies back to that question. Podcasting requires both the people to be present physically at one location. But recently, due to the pandemic, it is conducted online which most of the time results in poor quality of the audio. One of the reasons for the same is the presence of noise in it. This paper compares various noise reduction algorithms and also states the best algorithm to solve the above problem. We carried out our experiment on various audio files. Results were compared against various noise reduction methods and best ratio was obtained for Spectral Gating Algorithm.

TL;DR: In this paper, the authors focus on building an application where interview-based podcasts can be conducted at different geographical locations while preserving the audio quality using Spectral Gating and Speech Recognition algorithm.
Abstract: Podcasts contain information in an audio form which is being recorded in human voice. These recorded podcasts are later published on various podcast hosting websites where people can access and listen to various such podcasts. Podcasts can also be used to host an interview at a common location. But due to pandemic, the interviews are conducted through online platforms. The podcasts recorded via such platforms result in poor quality of the audio along with communication problems. To solve this problem, the paper focuses on building an application where interview-based podcasts can be conducted at different geographical locations while preserving the audio quality. Noise in the audio file is removed using Spectral Gating. Subtitles of audio file will also be generated using Speech Recognition algorithm. The final audio file will also generate an RSS feed link which can be used while publishing the podcast to notify subscribed users about the new updates. We have carried out our experiment on more than 100 audio files.
