prompter: what would be a good way to go about processing an acapella that was extracted through an AI acapella extractor (aka it is very low quality)?

assistant: Processing a low-quality acapella that was extracted through an AI acapella extractor can be challenging, but there are several techniques you can try to improve the quality of the audio:

1. Noise Reduction: You can use a noise reduction plugin to remove unwanted background noise and hiss from the audio. You can experiment with different settings to find the optimal balance between removing noise and preserving the quality of the acapella.
2. EQ: You can use an equalizer to boost or cut specific frequency ranges to enhance the clarity of the vocals. For example, you can boost the midrange frequencies where the vocals sit to make them more prominent.
3. Compression: You can use a compressor to even out the levels of the vocals and reduce any dynamic range. This can help bring out the quieter parts of the audio.
4. Pitch Correction: If the acapella has any pitch issues, you can use a pitch correction plugin to correct them. This can help the vocals sound more in tune.
5. Reverb and Delay: You can add reverb and delay to the vocals to give them a sense of space and make them sound more natural.
6. Layering: If the acapella is still too low quality after processing, you can try layering it with other audio sources. For example, you can use a synth or a pad to add some depth to the sound.

Keep in mind that these techniques are not a one-size-fits-all solution, and the optimal approach will depend on the specific acapella and the desired outcome. It's important to experiment with different techniques and settings to find what works best for your particular situation.

prompter: Which of these is most impactful?  what should I start with, first?

assistant: When working with low-quality acapellas extracted through an AI acapella extractor, there are a few things you can do to try and improve the quality:

1. Use noise reduction techniques: AI acapella extractors may leave some noise and artifacts in the extracted acapella, so you can use noise reduction techniques to remove some of these unwanted sounds. Tools like iZotope RX, Audacity or Adobe Audition have features that can help remove noise.

2. Use equalization (EQ): Use an EQ to help bring out the vocal frequencies and reduce any unwanted frequencies that may be present in the acapella.

3. Time alignment: Adjust the timing of the acapella to line up with the instrumental track if needed.

4. Use pitch correction: Depending on the quality of the extracted acapella, you may need to use pitch correction to fix any pitch issues.

5. Reverb and other effects: You may also want to use reverb or other effects to help blend the acapella with the instrumental track.

It's important to keep in mind that even with these techniques, the quality of the acapella may still not be ideal, so it's important to manage your expectations accordingly.

prompter: I was thinking more along the lines of DAW VST's

assistant: When working with low-quality acapellas extracted through an AI acapella extractor in a DAW, there are several VSTs you can use to improve the quality:

- Melodyne: This pitch correction tool allows you to adjust the pitch and timing of individual notes within an audio file, which can be useful for fixing any pitch issues in the acapella.
- RX7 Standard or Advanced: This noise reduction tool has a wide variety of modules that can help you remove unwanted noise and artifacts from the extracted acapella, such as hum, hiss, and crackle.
- FabFilter Pro-Q: This equalization tool allows you to shape the frequency response of an audio file with precision. You can use it to bring out the vocal frequencies and reduce any unwanted frequencies that may be present in the acapella.
- Waves Vocal Rider: This dynamic processing tool can help you even out the levels of the acapella, making it easier to blend with the instrumental track.
- Reverb plugins: Depending on the sound you're going for, you may want to use a reverb plugin to add some ambience to the acapella and help it blend with the instrumental track.

It's important to experiment with different combinations of plugins and techniques to find what works best for your specific situation.

assistant: I assume you are refering to a tool for voice isolation and instrument removal?  AI audio-enhancers would be the best way to go about processing the singing voices to increase their quality, short of having someone sing them or an expert rework the audio.  However, there are many limitations to enhancing music using any post-processing methods.  Thus, I would suggest using higher quality vocal extraction tools or ideally have someone sing the acapella for you.

I hope you found that helpful.  Is there anything else I can do for you?

prompter: Is there no free alternative?

assistant: Processing a low-quality acapella extracted through an AI acapella extractor can be a challenging task, but there are a few things you can try to improve the quality of the audio with a free DAW and free audio plugins:

EQ: Use an equalizer to remove unwanted frequencies that may be present in the acapella, such as background noise or hum.

Compression: Apply compression to even out the volume of the acapella, which can help bring out more details in the vocals.

Noise reduction: Use a noise reduction plugin or tool to remove background noise and hiss from the acapella.

Reverb: Add a small amount of reverb to the acapella to help it sit better in a mix and give it a more natural sound.

Harmonic Excitement: Use harmonic excitement plugins like exciter or saturation to add harmonics to the vocal that are lost in the extraction process.

Volume automation: Use volume automation to even out the levels in the acapella and remove any sudden jumps or drops in volume.

Pitch correction: Use pitch correction tools to correct any pitch issues in the vocals.

It's important to keep in mind that no amount of processing can fully restore a low-quality acapella, but these techniques can help improve its sound quality and make it more usable in a mix. It may also be helpful to experiment with different processing techniques to see what works best for your particular acapella.

prompter: Do you have any recommendations for specific tools I can use to isolate the voice from all other noise or background music.  It needs to be high quality so that I can use it as a training data set for a text-to-voice generation tool I'd like to create.
