When downloading from Enhance speech, we do not convert the format. Whatever format you import, you'll receive back in the download. For example, if you import an .mp3 file, you'll get back an .mp3 file.
On the free plan, you can process files up to 30 minutes in duration (maximum 500 MB), with a daily limit of 1 hour. On the Premium plan, you can process up to 4 hours of content per day, with individual files up to 1 GB in size. Learn more here.
Enhance speech is language agnostic and does not generate or translate across different languages. The results often depend on the speaker's audibility and the amount of background noise. It’s important to note that clearer and more polished inputs (speaker pronunciation and enunciation) will produce better outputs. This tool enhances audio by filtering out noise and artifacts, adjusting pitch and volume levels, and normalizing the audio.
First, check the supported formats to ensure you uploaded an accepted file type. If that is not the issue, check the daily limits enforced by your current plan. You can do this by navigating to your avatar and/or initials in the top right corner and viewing Enhance speech usage.
