BUG: Configured lossy_bitrate not used

Describe the Bug

When attempting to convert songs using the streamrip tool, it appears that the configured lossy_bitrate value is not being utilized. Instead, the default value of -q:a 0 is being used, resulting in an incorrect bitrate flag being passed to ffmpeg. This issue is particularly concerning for users who rely on the streamrip tool for high-quality song conversions.

Understanding the Importance of Bitrate

Bitrate is a critical factor in determining the quality of an audio file. A higher bitrate generally results in a higher quality audio file, while a lower bitrate may compromise on audio quality in favor of smaller file sizes. In the context of streamrip, the lossy_bitrate field is intended to specify the desired bitrate for lossy codecs, such as MP3. However, if this value is not being used, it may lead to inconsistent or suboptimal audio quality.

Command Used

The command used to reproduce the issue is as follows:

rip --quality 1 --folder . url <url>

This command is intended to convert the song to the specified quality and save it in the current directory. However, due to the lossy_bitrate issue, the conversion may not be performed as intended.

Debug Traceback

Unfortunately, there is no debug traceback available for this issue, as it is not related to a specific error or exception.

Config File

The relevant configuration file is as follows:

# Convert tracks to a codec after downloading them.
[conversion]
enabled = true
# FLAC, ALAC, OPUS, MP3, VORBIS, or AAC
codec = "MP3"
# In Hz. Tracks are downsampled if their sampling rate is greater than this. 
# Value of 48000 is recommended to maximize quality and minimize space
sampling_rate = 48000
# Only 16 and 24 are available. It is only applied when the bit depth is higher
# than this value.
bit_depth = 24
# Only applicable for lossy codecs
lossy_bitrate = 320

As can be seen, the lossy_bitrate value is set to 320, which is intended to be used as the desired bitrate for the MP3 codec.

Operating System

The issue is being experienced on a Linux operating system.

streamrip version

The version of streamrip being used is 2.0.5.

Screenshots and recordings

No screenshots or recordings are available to illustrate the issue.

Additional context

No additional context is available to provide further insight into the issue.

Investigating the Issue

To investigate this issue, we need to examine the code that handles the lossy_bitrate field in the configuration file. Specifically, we need to determine why the configured value is not being used and instead, the default value of -q:a 0 is being used.

Possible Causes

There are several possible causes for this issue:

Incorrect configuration file parsing: It is possible that the configuration file is not being parsed correctly, resulting in the lossy_bitrate value being ignored.
Default value override: The default value of -q:a 0 may be overriding the configured lossy_bitrate value.
Code logic error: There may be a logic error in the code that handles the lossy_bitrate field, resulting in the incorrect value being used.

Resolving the Issue

To resolve this issue, we need to identify the root cause and make the necessary changes to the code. This may involve updating the configuration file parsing logic, removing the default value override, or fixing the code logic error.

Conclusion

In conclusion, the lossy_bitrate field in the streamrip configuration file is not being used, resulting in an incorrect bitrate flag being passed to ffmpeg. This issue is critical for users who rely on the streamrip tool for high-quality song conversions. To resolve this issue, we need to investigate the code that handles the lossy_bitrate field and make the necessary changes to ensure that the configured value is used correctly.

Recommendations

Based on the investigation, the following recommendations are made:

Update configuration file parsing logic: The configuration file parsing logic should be updated to correctly handle the lossy_bitrate field.
Remove default value override: The default value override for -q:a 0 should be removed to ensure that the configured lossy_bitrate value is used.
Fix code logic error: The code logic error that results in the incorrect value being used should be fixed.

By implementing these recommendations, we can ensure that the lossy_bitrate field is used correctly, and the streamrip tool provides high-quality song conversions as intended.
Q&A: Configured lossy_bitrate not used

Q: What is the issue with the lossy_bitrate field in the streamrip configuration file?

A: The issue is that the configured lossy_bitrate value is not being used, resulting in an incorrect bitrate flag being passed to ffmpeg. Instead, the default value of -q:a 0 is being used.

Q: Why is this issue important?

A: This issue is important because it affects the quality of the audio files being converted by streamrip. If the lossy_bitrate value is not being used, the audio files may not be converted at the desired quality.

Q: What are the possible causes of this issue?

A: There are several possible causes of this issue, including:

Incorrect configuration file parsing
Default value override
Code logic error

Q: How can I resolve this issue?

A: To resolve this issue, you need to identify the root cause and make the necessary changes to the code. This may involve updating the configuration file parsing logic, removing the default value override, or fixing the code logic error.

Q: What are the recommended steps to resolve this issue?

A: The recommended steps to resolve this issue are:

Update configuration file parsing logic
Remove default value override
Fix code logic error

Q: What is the impact of this issue on streamrip users?

A: The impact of this issue on streamrip users is that they may not be able to convert audio files at the desired quality. This can result in poor audio quality or incorrect file sizes.
