Every year, neural networks become more advanced and perform many useful functions. Their application in affiliate marketing is growing, from writing appeals for account reinstatement to preparing statistical and video creatives.
Today, we will discuss the best neural networks for helping with voiceovers, enhancing audio quality, and removing noise and background sounds.
What Are These Neural Networks Useful for Affiliate Marketing?
The success of an advertising campaign primarily depends on the quality of the creatives.
Most experienced media buyers prefer to create short videos since static images cannot fully express a product's benefits and adequately convey customer emotions.
However, another problem often arises with short videos—while the visuals are striking, the audio quality leaves much to be desired. What to do?
Here’s a step-by-step algorithm:
1. Launch one of the neural networks from the list below;
2. Upload your audio recording or write a prompt (text request to the neural network);
3. In the editor, select the necessary settings and start the neural network;
4. Download the finished audio file and insert it into your creative.
Next, we will discuss the best services for audio work.
Top 10 Neural Networks
Auphonic
Auphonic is a platform for audio post-production.
The service allows you to:
- Suppress noise and music if you need only the voice recording;
- Adjust the volume between speech and background music;
- Remove unwanted frequencies and hiss for clean sound;
- Mix several audio tracks and eliminate cross-talk;
- Convert speech to text, automatically create footnotes and timestamps;
- Clean the audio of quiet fragments, pauses, and filler words (like “um,” “uh,” and “ah”) for English, German, and other languages.
Auphonic can be used for free; however, the number of credits allocated per month will allow for only 2 hours of audio processing.
Paid plans start at $11 per month (for 9 hours), and a one-time payment option (without a subscription) costs $12 for 5 hours.
ElevenLabs
One of the most well-known services for generating realistic speech is ElevenLabs, which appeared in 2022.
The platform's functionality allows you to:
- Convert text prompts into speech in 32 languages with 70 different voices;
- Duplicate the voiceover in another language;
- Create realistic sound effects;
- Generate a clone for creative voiceovers;
- Remove background noise from an audio file;
- Revoice your voice in someone else's voice.
The neural network can be used for free. You will have access to 10,000 characters per month for creating text prompts (approximately 10 minutes of audio).
Paid plans offer more characters and additional functions. The Creator level, at $22/month, with 100,000 characters and professional voice cloning, will be sufficient for affiliate work.
Audo Studio
Audo Studio offers to clean up audio in just 30 seconds.
This service helps to:
- Automatically remove background noise from recordings;
- Adjust speech volume with the push of a button;
- Neutralize echo in the made recordings.
The free plan allows for 20 minutes of audio improvement per month. If that’s not enough, you can switch to the $20 plan (600 minutes).
Cleanvoice AI
The Cleanvoice AI neural network helps to automatically clean files from noise and improve sound in 10 minutes.
The service can remove background hum (for example, from a fan or street noise) and filler words, prepare transcription of audio recordings and generate brief summaries.
Additionally, the neural network can identify and remove long pauses and unpleasant sounds (such as clapping, heavy breathing, stuttering, and so on). Furthermore, this platform can edit and balance volumes, softening or brightening voices.
The service lets you choose exactly what you want to enhance in the recording and at which segments.
The neural network's functionality allows you to add multiple audio tracks from different microphones, automatically synchronizing and correcting them to sound consistent.
There is a free trial for 30 minutes of audio processing and two paid subscription options: pay-as-you-go (starting at $11 for 5 hours with the option to top up as needed) and a classic monthly subscription (starting at $11 for 10 hours).
LALAL.AI Voice Cleaner
LALAL.AI is a web service that extracts clear voice and background sounds from audio and video.
For instance, if you like a competitor’s creative with dynamic music and need to extract the track to revoice it for a different market, you can upload the creative in a convenient format to the platform; the neural network will scan the recording and split it into two tracks: with voice and separately with music.
After processing, you can listen to the resulting recordings and save them to your computer.
In the free version, you can upload and process 10 minutes of audio up to 50 MB in sizes and in MP3, OGG, and WAV formats.
To download and upload files, such as MP4 files, you must pay at least $15 for 90 minutes.
The most cost-effective plan at LALAL.AI costs $35 for 500 minutes.
Adobe Enhance Speech
This tool is part of the Adobe Podcast suite. Enhance Speech is convenient because it automates everything without extra settings.
The user only needs to upload a recording in MP3 or WAV format, and the neural network will automatically remove echo and eliminate background noise. Additionally, Enhance Speech adjusts the volume and can even reconstruct speech to make the voiceover clearer.
Therefore, if specific phrases in a creative are difficult to hear, you can try extracting the sound and improving it with this neural network.
However, there are nuances. The neural network processes English recordings well, but there may be issues when working with other languages (such as Russian or French).
The program enhances recordings of up to 60 minutes in length and up to 1 GB in size.
In the free version, you can process only one file at a time, and the daily usage limit is 1 hour.
You can purchase an Adobe Express Premium subscription, which increases the limit to 4 hours per day and allows you to upload and process multiple files simultaneously. It also allows you to access other Adobe services (like 250 credits for using the company’s generative AI). The cost starts at $99 per year.
Krisp
Krisp differs from the previous services in that it is mainly used for video conferencing and call centers.
Krisp can suppress echo, noise, and background voices in real time, adjust accents in English and other languages, and generate a summary and transcription after the conversation or meeting ends.
To use Krisp, you need to download the app on Mac or Windows. It creates two virtual devices—Krisp Microphone and Krisp Speaker—that mimic a physical microphone and speaker.
Krisp supports over 800 different calling applications, including Zoom and Microsoft Teams.
In the free version, you can use Krisp for 120 minutes per week, but unlimited access costs $16 per month or $96 annually.
Audio Noise Reducer
Audio Noise Reducer is a mobile app for audio processing.
You can upload up to 50 MB of video or audio files, and the neural network will automatically remove background noise.
Positives include a simple interface and free access (with ads).
Users can choose a subscription for $3 per week, $10 per month, or a one-time fee of $35, which unlocks additional file formats.
AI-coustics
The AI-coustics service differs from the previous ones in that it allows you to manually adjust the level of sound processing. This is convenient if you need to maintain a certain background noise level in your creative work so the voiceover does not sound overly artificial.
The developers promise to enhance your sound to studio quality by automatically suppressing echo and reverberations, removing background noise, and clarifying speech.
The free version allows you to process 1 hour of audio per month. Processed videos will have a watermark, and each individual audio file must be no longer than 10 minutes and no larger than 100 MB.
Prices for the paid subscription start at $11 for 10 hours per month. Files can be up to 1.5 GB in size and up to 2 hours long.
Crystal Sound
Crystal Sound is similar to Krisp's operation mechanism — it acts as an intermediary between your microphone and various calling and audio recording applications.
Like Krisp, Crystal Sound helps eliminate background noise, echo, and extraneous voices in real time, enhancing and clarifying one's own voice.
In the settings, you can also choose the level of sound processing to make it sound natural or robotic.
The free plan gives you access to the main features for 90 minutes daily.
Paid plans start at $96 per year. In addition to unlimited real-time audio processing, they allow you to record calls and subsequently convert speech to text. The Elite plan ($348 per year) allows you to upload audio files.
Conclusion
Voiceover is an important part of the creative process and directly affects the ROI of the campaign.
In your work, you need to combine several services for audio processing. For example, the ElevenLabs platform will meet your needs for creating voiceovers from scratch, while Auphonic can enhance existing audio to studio quality.
To extract a preferred track from someone else's creative work, you can use the neural network within LALAL.AI. Crystal Sound or Krisp can also conduct a call with your team, even with a poor microphone and without any audio interference.
However, achieving quality sound in your creative is not enough. The creative must also address the needs of the target audience. A personal manager at the MyBid advertising network can assist with audience targeting; they are ready to provide tips on verticals and geos and will also independently launch and optimize your ad campaign with your creatives.
