---|---|---|---|---|---|---|
auphonic | 1st | 4th | 1st | Best overall quality, true to original audio | Minimum 30 seconds billing | 7 days |
cleanvoice | 2nd | 1st | 3rd | Excellent denoising, good overall | Can sometimes sound underwater when enhancing | 7 days |
sieve-resemble-enhance | 3rd | 2nd | 2nd | Cost-effective, very flexible | Not as refined as top options, distortative effects at times | 48 hours |
elevenlabs | 4th | 3rd | N/A | Incredible quality (when stable) | Distortative effects at times, no explicit enhance option, expensive | 3 years |

Unlike the third-party backends, you are billed for the compute time of the model with no minimum billing. This tends to be the cheapest option by an order of magnitude.
As a compute-based example, this 1-minute long audio with the noise
backend option cost us $0.0014.
As another compute-based example, this 1-minute-long audio with the enhance
backend cost us $0.0092.
