Cosmic Transcriber

Soh’s reviewed Windows 10/11 application for long MP3 lectures, interviews, podcasts, Dharma talks, folders, and multi-part recordings. Features resumable batch transcription, TXT/Markdown output, and two complementary OpenAI model modes.

Key Capabilities at a Glance

Engineered to handle long-form audio archives effortlessly, Cosmic Transcriber streamlines batch transcription with robust session state management and output flexibility.

📂 Batch Audio Processing

Drag and drop individual MP3 files or entire nested folder trees for hands-off queueing.

⚡ Resumable Checkpoints

Completed chunks are saved dynamically. Resume interrupted sessions without re-processing.

📝 Dual Export Formats

Outputs pristine plain text (.txt) or clean, formatted Markdown (.md) files automatically.

🔐 Secure Key Management

Optionally encrypt your API key locally using native Windows DPAPI user protection.

Examples of Use & Ideal Workflows

Cosmic Transcriber is tailored specifically for long-form, complex speech content where accuracy and context preservation matter most:

Spiritual & Scholarly

Dharma Talks & Spiritual Lectures

Perfect for multi-hour retreats, oral teachings, and technical Buddhist philosophy. Pair with gpt-transcribe to preserve specialized Pali/Sanskrit terminology and delicate negations while significantly minimizing hallucination risks.

Interviews & Media

Podcasts & Panel Interviews

Process multi-speaker recordings using gpt-4o-transcribe-diarize to automatically segment dialogue into distinct speaker turns accompanied by timestamps.

Archival Collections

Multi-Part Audio Series

Load entire multi-part series or nested folder hierarchies in a single step. The app handles long-file chunking and tracks completion checkpoints file by file.

Publication Quality

Two-Pass Editorial Pipeline

Combine the raw verbal fidelity of gpt-transcribe with the structural turn labels of gpt-4o-transcribe-diarize in ChatGPT to generate publication-ready transcripts.

Choose the Model by Purpose

Cosmic Transcriber supports two complementary OpenAI model modes. Selecting the appropriate model for your recording type ensures the best balance between wording fidelity and speaker structure.

gpt-transcribe (Default)

The newer high-accuracy general model. Use it as the controlling text when exact wording, specialist terminology, multilingual speech, and negations matter.

• Supports language hints, literal keywords, and recording context.
• Provides maximum wording fidelity and term accuracy.
• Note: Does not add speaker labels in the app’s current file workflow.

gpt-4o-transcribe-diarize

The older specialised speaker-labelled model. It identifies speaker turns and can include timestamps throughout the audio.

• Identifies individual speaker turns (Speaker A, B, etc.) and timing.
• Note: Cosmic Transcriber does not send prompt/context or structured keyword hints in this mode.
• Note: Speaker letters may reset between independently processed Parts.

Soh’s Recommended Two-Pass Method

Transcribe the same recording once with gpt-transcribe for the most reliable wording and once with gpt-4o-transcribe-diarize for speaker structure. Upload both outputs to ChatGPT; tell it to keep the first transcript as the wording authority and use the second only for speaker labels, timestamps, and turn boundaries. Ask it to mark uncertain alignments instead of guessing.

Copy-Paste Prompt for ChatGPT:

I am providing two transcripts of the same recording. Treat the gpt-transcribe output as controlling for exact wording, names, technical terms, negations, repetitions, and sentence content. Use the gpt-4o-transcribe-diarize output primarily for speaker labels, timestamps, and turn boundaries. Do not invent speech or speaker identities. Mark uncertain alignment instead of guessing.

Get an OpenAI API Key

1. Sign in to the OpenAI API key page and create a new secret key.
2. Set up API billing in the OpenAI Platform billing page. API usage is billed separately from a ChatGPT subscription.
3. Copy the key once and keep it private. Do not post it, place it in public files, or share it with other people.

Quick Use Guide

1. Download and extract the ZIP, then start Cosmic Transcriber normally rather than as administrator.
2. Enter the API key for the session, load it from OPENAI_API_KEY, or optionally save it for the current Windows user using Windows DPAPI.
3. Add MP3 files or folders, choose the model and output options, then start transcription. Compatible completed chunks can resume from checkpoints.

CloudScribe Pro: Turn Text into MP3

Install: download the Windows ZIP, extract it fully, then follow the setup and user guide to launch the app and configure your own Google Cloud credentials. Google Cloud service usage may incur charges.

CloudScribe Pro is a Windows text-to-speech app that uses your own Google Cloud Text-to-Speech account to turn reviewed articles, translations, or transcript passages into MP3 audio. It includes saved voice and language setups, a Help walkthrough, cost review before generation, and MP3 playback and export.

Set up, then generate: first-time use requires your own Google Cloud project, enabled billing and Text-to-Speech API, and service-account credentials. Follow the guide, choose a voice, review the text and cost, then approve generation. Split long text into passages and review each part as described in the guide; this is not a promise of automatic full-book narration, batch synthesis, or MP3 joining.

Pair the tools: use Cosmic Transcriber for the recording-to-text stage, check and edit the transcript, then bring selected text into CloudScribe Pro. The result is synthetic narration, not the original recording or a reproduction of the original speaker’s voice.

Costs and privacy: Google Cloud speech usage may incur charges on your own Google Cloud account, separate from Cosmic Transcriber’s OpenAI API bill. Submitted text is sent to Google Cloud for speech synthesis. Keep credentials private and check costs before generating.

Back to the two-tool overview

Technical Scope: Windows-only, MP3-oriented, internet-dependent completed-file transcription. It is not a live microphone recorder or audio editor. Speaker-labelled output is available only in diarization mode. Current model availability and pricing can change; check OpenAI’s current API pricing.
