Update and fix

[Haurrus]

Server.py :

Modified the class section to add optional argument like path to output the audio for the endpoint tss_to_audio speaker_wav is also optional because I added failover mechanism into the tss_funcs.py to failover to reference.wav from finetuned models. So there's this new import : from typing import Optional And created a TTSStreamRequest class because this endpoint was the only one without class.

Also modified this line to match the default one in main.py : MODEL_FOLDER = os.getenv('MODEL', 'xtts_models')

tts_funcs.py :

added this import at the start : import torchaudio.transforms as T I use it to format the audio output to a more standardly used encoding so it can be used widly without degradation So the def local_generation have been widly modified because of this (maybe I should modify the stream_generation in the same manner)

in def process_tts_to_file : added a failover mechanism to use the reference.wav from the loaded model if it exist.

Walkthrough

The xtts_api_server underwent updates to enhance functionality and user experience. The server now allows specifying a save path for synthesis requests, and a new streaming request class was introduced. The TTS endpoints have been refined for better audio processing and model management. Additionally, the server's listening port was changed to 8020.

Changes

File Path	Change Summary
xtts_api_server/server.py	Added save_path to SynthesisRequest and SynthesisFileRequest, introduced TTSStreamRequest, updated tts_stream endpoint, added save_path to tts_to_audio endpoint, changed server port to 8020.
xtts_api_server/tts_funcs.py	Imported torchaudio.transforms, added switch_model method, updated stream_generation for audio processing, added speaker path checks in process_tts_to_file, refactored local_generation for TTS.

🐇✨ To save a path, or stream a voice so clear, The server hops to 8020, with nary a fear. With audio transforms, and models to switch, The rabbit's code leaps, without a single glitch. 🎶🌟

Tips

### Chat There are 3 ways to chat with CodeRabbit: - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit-tests for this file.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.

my bad again, I should have created a custom branch to just pull request on the two file I wanted a merge on.

So the pull request is mainly focused on these two :

xtts_api_server/server.py

xtts_api_server/tts_funcs.py
