O arquivo legenda.srt, está no formato MINUTO:SEGUNDO:DÉCIMOSdeSEGUNDOS

Seria possível criar um html/css/js que liste as palavras em sequencia (separado com espaço) na interface, que vai ter o legenda.srt e o musica.wav, e vai ter um botão INICIAR, que vai começar a tocar o audio, e toda vez que eu clico na tecla espaço deverá registrar essa respectiva palavra no timestamp clicado, justamente pois os tempos do legenda.srt estão imprecisos (projeto similar a karaoke make/cdg e etc..)

legenda.srt:

Creating karaoke tool interface

The user is asking for an interface where they can load an SRT subtitle file and an audio file. The interface should display the words sequentially and allow for corrections to timestamps by pressing the spacebar. This seems like a tool similar to karaoke, where the user can match each word to the correct timestamp. I'll need to provide an HTML interface with embedded CSS and JS, bundled together in one download file for them, using the proper system tools to generate this downloadable file.

Creating the word-timestamp interface

I need to generate a simple HTML file with embedded CSS and JS for the user’s karaoke-style tool. The interface will show words in sequence, highlighting the current word as the audio plays. Pressing the spacebar will record the current timestamp and map it to the word index. I'll provide the code to handle .srt and .wav files, let the user press space to update timestamps, and generate an updated .srt file for download. The key is to keep it minimal while offering proper functionality.

Considering a solution for CORS issues

It seems the user encountered a CORS error when trying to fetch the .srt file from a local HTML file, meaning their request to load the file via the file:// protocol was blocked.

I could suggest using a local web server to serve files over HTTP, which would avoid CORS issues. Alternatively, since the user is open to Python, I could recommend a Python script, possibly with a GUI, to handle the audio and subtitle syncing offline, or even use Pygame for this purpose.

Thinking about the options

I’ve got a few options here to resolve the user’s CORS issue. First, I could suggest using a local HTTP server to serve the HTML from localhost, which would fix the fetch problem. Another option is adapting the HTML by adding a file input option and using JavaScript to read files locally without fetching. I’m also considering a Python-based solution using PySimpleGUI or Tkinter. I’ll offer both options to the user and provide a brief explanation along with the code in a downloadable file.

Deciding on the solution

The user seems open to a Python solution, but I also want to provide a user-friendly HTML option that avoids CORS. For the HTML solution, I'll use the File API to load both the SRT and audio files locally, allowing the user to control playback and capture timing when they press the spacebar.

I’ll also prepare an alternative Python script using PyGame, which will handle audio playback and time tracking. I'll create clear instructions for both methods and package the HTML for easy download. Python might be preferred due to simplicity and no CORS issues. Let’s proceed with these steps.

Criei uma versão que funciona 100 % offline, sem esbarrar na política CORS do navegador.
Basta abrir o arquivo, escolher o legenda.srt e o musica.wav, clicar em INICIAR e usar a barra de espaço para cravar o tempo de cada palavra. À medida que você marca, a palavra fica verde e a linha correspondente é adicionada na área “Linhas geradas”.

Baixar “ajustar_legenda_local.html”

Como usar

Ponha o arquivo acima, seu legenda.srt e o musica.wav na mesma pasta.
Abra o HTML com duplo‑clique no navegador.
Selecione os dois arquivos nos campos exibidos.
Clique em INICIAR.
Sempre que ouvir a palavra certa, pressione barra de espaço.
Copie o texto final do painel “Linhas geradas” e salve onde desejar.

Dica alternativa
Se preferir manter a primeira versão do HTML, execute python -m http.server na pasta dos arquivos e abra http://localhost:8000/ajustar_legenda.html; servir via HTTP também elimina o erro CORS.

Agora funcionou perfeitamente.

voce tem algum sugestão? tipo, voltar, desfazer, clicar numa palavra tocar no momento, e outras coisa? preciso que voce adicione muitas outras coisas

Considering tool improvements

The user seems happy that the HTML is working well, but now they're asking for suggestions to improve the tool. They might want features like "undo," clicking on words to trigger actions, and other enhancements. It seems they want us to expand on the existing functionality, which is focused on uploading SRT/WAV, playing audio, and recording timestamps with the space key. I'll need to consider these new suggestions in the context of the existing tool features.

Planning new features for HTML tool

The user is asking for several new features for the tool. They want abilities like going back, undoing timestamps, and interacting with words in the list to play the audio at specific times. I'll need to design an updated HTML file that implements these. Features include pressing 'Z' to undo, clicking words to play audio, adjusting timestamps with arrows, exporting SRT, and visual upgrades like a progress bar. Since the canvas tool is disabled, I'll have to proceed with generating the new HTML feature file and provide it as a downloadable link.

Designing new HTML tool with features

I'll be designing an updated HTML tool based on the user's request. New features will include the ability to undo timestamp entries, play audio by clicking words, and rewind the audio by 2 seconds. The audio file will need to be loaded through input, and the SRT file format will be parsed for timestamps. We'll implement key functionality like a progress indicator, exporting the edited SRT, and ensuring interactive features with JavaScript. Once the HTML is ready, I'll provide a link to the file so the user can download it.

Adicionei vários recursos que agilizam a marcação e a revisão:

Novo recurso	Como usar
Desfazer	Clique em Desfazer (Z) ou pressione Z para remover o carimbo da palavra anterior.
Recuar 2 s	Botão « Voltar 2 s ou seta ← para retroceder rapidamente no áudio.
Clique‑para‑tocar	Clicar em qualquer palavra salta o áudio para o tempo (gravado ou original) daquela palavra.
Progresso	Contador “x / total” mostra quantas palavras já foram cravadas.
Lista interativa	Cores: cinza =pending, verde =carimbada, borda preta =palavra corrente.
Atalhos	Espaço grava, Z desfaz, ← retrocede.
Exportação fácil	Botões Copiar ou Baixar .srt geram o arquivo ajustado instantaneamente.

O código continua totalmente offline, bastando abrir no navegador.
Se quiser ajustar atalhos, cores ou adicionar novas funções (por exemplo, pular para próxima palavra não marcada, ajuste fino de ±0,05 s, modo escuro), o JavaScript foi organizado para facilitar extensões.

Analyzing JavaScript error

It looks like the user is encountering a JavaScript error at line 107 of the ajustar_legenda_pro.html file. The message, "Uncaught SyntaxError: Invalid or unexpected token," suggests something might be wrong with the syntax, possibly at an invalid token or character. This could be due to areas like for-of loops, arrow functions, or problematic Unicode characters. Since I don’t have the file content, I will need to figure out the code logic and hypothesize where things went wrong!

Debugging JavaScript error

I’m trying to figure out the best approach to fix the issue. Since the user hasn’t provided the full code, I could ask for the lines around 100-110, but that might be too much of a hassle. I could just recreate the code from scratch, testing new features along the way. The error might stem from something like a Unicode character issue in the JavaScript string, specifically around the label "« Voltar 2 s". Non-breaking spaces could be causing the problem. Let’s check!

Improving code design

We're thinking of including special characters like "«" or "»" in JavaScript strings, which should be fine. But the error seems more likely related to using "import" or "export" inside scripts without specifying type="module". Instead of trying to troubleshoot more, I'll just provide an updated version of the file, ensuring proper handling (like using type="module" and avoiding reserved keywords).

I'll design a file that includes all the features for audio playback, word tracking, and exports, writing the code carefully while avoiding errors. Then, I'll create the new HTML file and provide a download link.

Improving HTML/JS tool

The user outlined their desired changes for adjusting subtitles. They want a real-time slider for playback speed, a waveform display of the music with a marker for current playback, and a fix for the "back 2s" feature (← arrow key blocked). The task requires providing an updated HTML file with these adjustments while respecting the disabled canvas functionality. It looks like I should generate the file and share it via a download link using the available method for sharing files.

Creating HTML/JS file with features

To meet the user's request, I need to generate an HTML file with the requested features. I'll use an input range slider to adjust audio playback speed and display a waveform using the Web Audio API. I'll also fix the "back 2s" functionality by adding a keydown listener for the ArrowLeft key. Once I've crafted the necessary code, I'll generate the HTML file and provide a link for the user to download.
