1. Audio and Video Recording
ポッドキャスト: Records up to 4K video and lossless wav audio for every participant. Each person’s audio track is captured locally on their device. This dual-recording approach gives you separate tracks for clean editing without internet drops hurting sound quality.
変更: Does not include a recording studio. Voice creators need to record their voice recordings elsewhere first. Then you import the audio files into the next generation audio editor for voice editing and morphing.
⚠️ 警告： If you need to do remote interviews or capture podcast episodes, Altered cannot help. You will need a separate tool like Riverside or Audacity alongside it.
2. AI Powered Audio Processing
ポッドキャスト: Magic Dust is the standout AI powered audio processing tool. One click handles noise cancellation, silence removal, and auto leveling. It automatically enhances every audio file. Many users call it a game changer for improving sound quality and adding a professional studio touch to any recording.
変更: Offers an AI Voice Cleaner that removes background noise, voice fillers, and mouth artifacts. It also normalizes audio quality across tracks. The tool is effective but focused only on voice editing, not music or sound effects.
3. AI音声クローニング
ポッドキャスト: Includes basic voice cloning through its AI Voices Hub. You can clone your own voice and use it for text to speech narration. The cloned voice works for podcast intros and quick voiceovers in podcast episodes.
変更: AI voice cloning is Altered’s specialty. The rapid voice clone feature creates a realistic copy of any voice from a few seconds of audio. The voice cloning technology preserves emotion, timing, and delivery for high quality voice content.
4. 音声モーフィング
ポッドキャスト: Does not offer speech-to-speech voice morphing. You can use AI voices for text to speech, but you cannot transform your own voice into a different character or accent.
変更: This is where Altered Studio truly shines. The advanced voice ai technology lets you record in your own voice, then morph it into any multiple voice option from the extensive voice library. Change characters, accents, and styles while keeping your emotion and acting intact.
5. Text to Speech
ポッドキャスト: Features over 1,000 vibrant AI voices powered by its Asyncflow v1.0 model. Type text and get natural-sounding ai generated voices in seconds. It’s great for creating audio content like podcast intros and voiceovers.
変更: Offers premium text to speech with 14 speaking styles. Whisper, shout, or speak conversationally. The portfolio TTS voices support 75+ languages through multiple voice ai technologies in one place.
6. Video Editor and Video Content
ポッドキャスト: Includes a full ビデオエディター with a drag-and-drop timeline. You can trim clips, add transitions, and switch between camera angles. Perfect for producing video content, video podcasts, and ユーチューブ エピソード。
変更: Does not include video editing features. Altered focuses entirely on voice and audio storytelling. You would need a separate online audio editor or video tool for any visual content.
7. Real Time Voice Changer
ポッドキャスト: Does not offer a real time voice changer. Its AIツール work during post-production only. You cannot change your voice during a live voice chat or gaming session.
変更: The real time voice changer works on Discord, Zoom, and Skype. Real-Time Performance uses only 1-4 CPU cores for ultra-low latency morphing for live calls or gaming. Effective noise cancellation keeps voice chats crisp.
8. Hosting and Publishing
ポッドキャスト: Gives you a dedicated podcastle page and distributes your entire podcast to all major podcast networks. Apple Podcasts, Spotify, and other directories are supported. Monitor performance from one dashboard.
変更: Has no podcast hosting or publishing features. Altered is designed for voice content creation, not content distribution. You would need a separate hosting service to publish your shows.
