Q: What can vocal separation technology do?

A: Vocal separation technology allows us to isolate vocals and accompaniment from an audio file, creating two separate tracks. This technology has a wide range of applications. You can use it to extract clear vocals or accompaniment, convert video files into audio, or create silent, vocal-removed, or accompaniment-removed versions for videos. Whether it's for music creation, karaoke production, audio editing, or content production, vocal separation is a very useful tool.

Q: What is instrument separation technology?

A: Instrument separation technology is an advanced audio processing method that can identify and isolate various instrumental parts in an audio file. With this technology, you can extract individual tracks for specific instruments, such as guitar, piano, drums, etc. This is incredibly helpful for mixers, music producers, and anyone who wants to study or recreate music, providing deeper control and innovative possibilities for musical works.

Q: How do I adjust the volume of specific sounds in the audio?

A: On the detail page, you will find a sound control switch in the upper right corner. Click it, and use the appearing sliders to adjust the volume of vocals, accompaniment, etc. After making adjustments, you can preview and directly download the adjusted audio file to obtain the track that meets your needs. This feature is particularly useful for music editing and creation that requires meticulous volume control.

Q: Will logging in with a mobile phone number and WeChat QR code create the same account?

A: Please note that logging in with a mobile phone number and WeChat QR code will create two separate accounts. Although both login methods provide access to our services, they are considered different accounts in our system, each with its own membership duration, time cards, and user data. To manage your benefits consistently, we recommend choosing one login method and sticking to it. If you need to merge accounts or transfer data, please contact our customer service team for assistance.

Q: I clicked to download a video, but the progress seems to be stuck at 'downloading' – why is this happening?

A: Downloading a video can take some time, especially when dealing with larger files or if the internet connection is slow. Please be patient and wait for the download to complete. If there's no progress for an extended period, you may need to check your network connection or try again later. If the issue persists, please contact customer support for further assistance.

Q: Is the 1800 minutes of time included in the membership services usually sufficient?

A: Yes, the 1800 minutes of time provided by the membership service is generally sufficient for most users. These minutes can be used for vocal separation, instrument separation, and adjusting the volume of specific sounds in tracks. Whether you are a music enthusiast, karaoke producer, or professional audio producer, this duration should meet your basic needs. If you need more time, you can always purchase additional add-on packages.

Q: How is my usage time calculated?

A: Currently, the usage time is calculated based on the duration of the uploaded audio files, ensuring that every minute of use is accurately recorded.

Q: How long is the validity of the membership?

A: Your membership is valid for 31 days, starting from the date of purchase. During this period, you can enjoy all the membership services.

Q: My membership has expired, how do I renew it?

A: Renewing is very simple. Just log into your account before or after your membership expires and select the renewal option to extend your membership services.

Q: What should I do if I run out of membership time?

A: If you need more time, you can purchase add-on packages to increase your usage duration. These add-on packages will be valid within your membership period.

Q: Do add-on packages have an expiration date?

A: Add-on packages are synchronized with your membership status. As long as your membership is valid, you can use the add-on packages. Any unused add-on packages will be retained after renewal.

Q: How will my membership time and add-on package duration be used together?

A: When you have both a membership and an add-on package, the system will automatically prioritize the consumption of your monthly membership time. Thus, the minutes from your add-on package will only start being used after the monthly time has been fully utilized. This ensures that you can maximize the use of all purchased time resources.
