Improve the sound in several short videos

I want to combine 2 songs with very different beats, one is boring and the other is fun, but I want the second song to be mixed like a DJ does, where it kind of overlaps and so on, so it looks cool. At the end of the song, I want to add the same boring one again, but I want it all to come together. And I want this to be done online.

Project description: Hello! I have a specific audio recording (content 18+). The recording contains sounds and voices of a sexual nature (moans, soft whispers, or speech). In the background, a television is also quietly running, and its sounds blend with the main background, making it difficult to discern the words. A lot of it cannot be heard by the human ear at all. The total duration of the file is 43 minutes, but it is mostly quiet. Special attention needs to be paid to the following timestamps (there are definitely sounds/phrases that need to be maximally amplified and cleaned up): 17:29 17:38 19:06 20:24 21:23 21:28 23:52 28:58 29:53 What needs to be done: 1. Using professional software (for example, iZotope RX), mute the television and maximally extract/make the quiet voice intelligible at the specified intervals. 2. Create a text transcription of the heard words. Important: Please include a short demo test (literally 10–15 seconds of processing any of the specified timestamps) in your response so I can assess whether you can extract the voice. I am attaching the file. I am looking for a performer who will tolerate the specifics and process the sound qualitatively. I await your proposals regarding price and deadlines. Thank you! Don't forget to attach the audio file before you hit the publish button. Good luck, a master will definitely be found! I will provide the file to the selected performer or send it in personal messages after the project is published.

Hello! I need to improve the quality of an audio recording for clear understanding of the words. Here are the task details: The conversation of a person is poorly audible due to strong background noise from a car engine. The engine sound is monotonous but drowns out the useful signal (speech). Additionally, the voice sounds muffled as the conversation was conducted through a speakerphone. The duration of the recording is approximately 15-20 minutes. Maximize the suppression of the low-frequency rumble of the engine, raise the intelligibility frequencies of speech (range 1–4 kHz), and make the words clear for transcription (minutes). Special requests: It is important not to "squash" the sound with AI filters so that the voices do not turn into robotic metallic artifacts. If it is impossible to completely remove the rumble without harming the speech, it is better to leave some noise but preserve the articulation of the words and ensure that both speakers are understandable.

Transcribe the audio file. Convert it into printed text while preserving the exact meaning. The audio has noise. Duration - about 1 hour.

Audio 30 minutes with noise. Transcribe the conversation of each participant into text, excluding sounds from the television and the street.
