Improvement of the recording from the dictaphone for complete understanding of the words

Budget: 1500 UAH Deadline: 1 day

Good day! I cleaned similar recordings — I remove the monotonous hum of the engine with a high-frequency cut and a spectral gate according to the noise profile, while I enhance the speech specifically in the range of 1-4 kHz so that the words are clear. I understand your wish not to over-compress: it's better to leave a bit of background than to make the voices sound like metallic robots. First, I will send you a trial of 1-2 minutes so you can hear the result, and then I will finish the entire recording. I will start today and will manage it within a day.

Hello! I have carefully reviewed the problem statement and can confidently formalize that I am ready to take on this project. I have extensive experience in sound engineering, particularly in methods of restoring various materials. Recently, I even created an entire composition using just one sound: https://www.youtube.com/watch?v=ULx4OmlmEI8&t=171s

I am happy to communicate regarding collaboration and will answer all questions.
Sincerely, Vitaliy.

Good afternoon, I worked as a sound engineer in the national theater. I will make the sound listenable and pleasant to the ear!

Hello!

💥 I will improve the recording quality without any AI!
🔥 Only old-school sound engineering with plugins — and manual parameter selection for each fragment!
🔥 On my studio monitors and studio ears.
👻 I have already processed a test fragment. But it's unclear where I can upload it.

Good day!

I understand the task: it is necessary to improve the recording from the dictaphone (remove noise, equalize the voice, create quality voiceover).

I have experience in audio processing: noise reduction, equalization, voice enhancement, adding effects. I will make the recording clean and pleasant to listen to.

I am ready to do a test fragment for you to evaluate the result.

I look forward to collaborating.

Good day!
I have reviewed your task. I understand that the main goal is to maximize speech intelligibility, rather than completely removing noise at any cost.
During the processing, I will focus on reducing the monotonous engine noise, improving the clarity of voices, and preserving the natural sound without excessive artifacts. If it is impossible to completely remove the noise without losing speech quality, the priority will remain on the clarity of the words.
I am ready to start immediately after receiving the recording.

Hello! I am ready to complete your task. I will write a custom Python script (using a Butterworth high-pass filter and adaptive noise suppression). This will allow cutting out the monotonous hum of the engine, enhancing the speech frequencies (1–4 kHz) for word clarity, and preserving the naturalness of both speakers' voices without a robotic effect. Feel free to reach out!

Hello! I have experience in audio processing using Python. For your task, I will use a combination of spectral subtraction and adaptive filters to remove engine noise without damaging the formants of the human voice. I can adjust the parameters to maintain the naturalness of speech and avoid the "metallic" artifacts typical of aggressive AI filters. I am ready to take on the work and provide a result suitable for high-quality transcription. Let's discuss the details; I am ready to start!

Good day!

I am ready to perform professional audio processing with a focus on maximizing speech intelligibility.

I understand the specifics of the task: it is necessary to reduce the monotonous engine noise, improve the clarity of voices, and preserve the natural sound without the characteristic "metallic" artifacts that often arise after excessive processing with AI filters.

During the work, I use a combined approach: spectral noise reduction, equalization, attenuation of low-frequency rumble, processing of the speech range, as well as manual adjustment of parameters to achieve the best balance between cleaning the recording and the naturalness of the voices.

As a result, you will receive:

* a maximally cleaned audio recording;
* a version preserving the natural sound of the voices;
* a file optimized for further transcription (stenography).

If it is impossible to completely remove noise without losing speech quality, I will prefer to maintain clear articulation and intelligibility of words, leaving only the minimally necessary background noise.

I am ready to start working immediately after receiving the recording. Expand

Hello!

I can help improve the quality of this audio recording. I work with sound cleaning and understand that in this case, the main goal is not just to remove noise but to make the speech as clear as possible.

During processing:

- I will minimize the monotonous engine noise without losing voice quality;
- I will emphasize the frequency range responsible for speech clarity (approximately 1–4 kHz);
- I will avoid excessive processing with AI filters to prevent metallic or "robotic" artifacts;
- if it is impossible to completely remove the noise without harming the voices, I will leave a small portion of it but maintain the natural sound and articulation of both speakers.

After processing, I will provide a finished file that is as suitable as possible for further transcription (transcripts).

I would be happy to discuss the details and get started on the work. Expand

Hello! I work with the restoration of audio recordings: I will remove the low-frequency hum of the engine (filters + spectral noise reduction), enhance the clarity in the range of 1-4 kHz, and equalize the muffled sound from the speakerphone. The processing is delicate, without aggressive AI filters - the voices will not sound metallic, and if needed, I will leave some background for the articulation of both speakers. I will create a test fragment of 1-2 minutes - you can evaluate the result before payment.
