206-227: Optimize file size stability check to reduce processing timeThe
isFileSizeStablefunction currently checks the file size three times with a 2-second sleep in between, totaling at least 4 seconds per file. This could slow down the processing if there are many files. Consider reducing the number of checks or the sleep duration, or implementing a more efficient mechanism to detect if a file is still being written to.
284-290: Simplify file extension handling withstrings.TrimSuffixThe code for removing the
.wavand.flacextensions from the output path can be simplified usingstrings.TrimSuffix. This improves code readability and reduces potential errors.Apply this diff to simplify extension handling:
outputPath := filepath.Join(settings.Output.File.Path, filepath.Base(path)) ext := strings.ToLower(filepath.Ext(outputPath)) - if ext == ".wav" { - outputPath = outputPath[:len(outputPath)-4] - } else if ext == ".flac" { - outputPath = outputPath[:len(outputPath)-5] + outputPath = strings.TrimSuffix(outputPath, ext)internal/myaudio/readfile.go (1)
64-64: Refactor to avoid redundancy in extension handlingThe code for obtaining the lowercase file extension is repeated. Consider creating a helper function to avoid redundancy and enhance maintainability.
Apply this diff to refactor the extension handling:
+func getLowercaseExt(path string) string { + return strings.ToLower(filepath.Ext(path)) +} ... file, err := os.Open(settings.Input.Path) if err != nil { return err } defer file.Close() - ext := strings.ToLower(filepath.Ext(settings.Input.Path)) + ext := getLowercaseExt(settings.Input.Path)internal/analysis/file.go (1)
68-72: LGTM! Consider enhancing the error message.The case-insensitive extension check is a good approach. However, the error message could be more user-friendly by listing the supported formats.
- return fmt.Errorf("\033[31m❌ Invalid audio file %s: unsupported audio format: %s\033[0m", filepath.Base(filePath), filepath.Ext(filePath)) + return fmt.Errorf("\033[31m❌ Invalid audio file %s: unsupported audio format: %s (supported formats: .wav, .flac)\033[0m", filepath.Base(filePath), filepath.Ext(filePath))

99-104: 🛠️ Refactor suggestionReconsider the use of
os.OpenFilefor file locking detectionThe
isFileLockedfunction currently determines if a file is locked by attempting to open it with read-write permissions. However, failure to open a file might not necessarily indicate that the file is locked; it could also be due to permission issues or the file being deleted. Consider a more reliable method to check if the file is being written to, such as checking if the file size is stable or using platform-specific file locking mechanisms.
369-370:⚠️ Potential issueReturn after logging error when creating output directory

Handle errors consistently in isFileReadyForProcessing
In isFileReadyForProcessing, when verifyAudioFile returns an error, the function logs the error but does not return it, instead returning false, nil. Similarly, when isFileSizeStable returns false, the function returns false, err, where err could be nil. This inconsistency could lead to suppressed errors. Ensure that all errors are appropriately returned and handled.

Consider endianness when reading WAV header fields
The calculation of expectedSize in verifyAudioFile reads bytes directly to form an integer. This assumes little-endian byte order. However, WAV files are typically stored in little-endian format, but it's safer to explicitly specify endianness. Use binary.Read with the appropriate endianness to correctly parse the header fields.
Apply this diff to use binary.Read for correct parsing:
+import "encoding/binary"

91-92: Handle errors when removing stale lock filesThe error returned by
os.Remove(outputPathProcessing)is not being checked. Ignoring errors from file operations can lead to unintended behavior if the file cannot be removed.Apply this diff to handle the error:
if isLockFileStale(outputPathProcessing) { log.Printf("Removing stale lock file: %s", outputPathProcessing) - os.Remove(outputPathProcessing) + if err := os.Remove(outputPathProcessing); err != nil { + log.Printf("Error removing stale lock file %s: %v", outputPathProcessing, err) + } return false }
338-344: Simplify file extension handling usingstrings.TrimSuffixCurrently, the code manually strips the file extension based on its length, which can be error-prone and less readable. Using
strings.TrimSuffixsimplifies the code and makes it more maintainable.Apply this diff to simplify the extension handling:
outputPath := filepath.Join(settings.Output.File.Path, filepath.Base(path)) ext := strings.ToLower(filepath.Ext(outputPath)) - if ext == ".wav" { - outputPath = outputPath[:len(outputPath)-4] - } else if ext == ".flac" { - outputPath = outputPath[:len(outputPath)-5] - } + outputPath = strings.TrimSuffix(outputPath, ext)
412-414: Continue directory traversal on access errorsReturning an error in the
filepath.WalkDirfunction will terminate the directory traversal. To ensure all accessible files are processed, log the error and continue with the traversal when an access error occurs.Apply this diff to handle errors gracefully:

36-41: Consider removing redundant context check before writeResults.While the context check before processing is crucial, the second check before writeResults might be unnecessary as:
- Writing results is typically a quick operation
- If cancellation occurs during writing, it's better to complete the write than leave partial results
- // Check for context cancellation before writing results - select { - case <-ctx.Done(): - return ctx.Err() - default: - } - return writeResults(settings, notes)Also applies to: 56-61
83-89: Optimize file handling to avoid double open.The file is being opened twice:
- First to check validity
- Again in GetAudioInfo
Consider removing the explicit file open and rely on GetAudioInfo for validation.// Check file extension (case-insensitive) ext := strings.ToLower(filepath.Ext(filePath)) if ext != ".wav" && ext != ".flac" { return fmt.Errorf("\033[31m❌ Invalid audio file %s: unsupported audio format: %s\033[0m", filepath.Base(filePath), filepath.Ext(filePath)) } - // Open the file to check if it's a valid audio file - file, err := os.Open(filePath) - if err != nil { - return fmt.Errorf("\033[31m❌ Error opening file %s: %w\033[0m", filepath.Base(filePath), err) - } - defer file.Close()
301-302: Enhance error context for cancellation.Consider wrapping the context error with additional information about the processing state.
